bauh (ba-oo), formerly known as fpakman, is a graphical interface for managing your Linux software (packages/applications). It currently supports the following formats: AppImage, ArchLinux repositories/AUR, Flatpak, Snap and Web applications.

Key features

  • A management panel where you can: search, install, uninstall, upgrade, downgrade and launch you applications (and more...)
  • Tray mode: it launches attached to the system tray and publishes notifications when there are software updates available
  • System backup: it integrates with Timeshift to provide a simple and safe backup process before applying changes to your system
  • Custom themes: it's possible to customize the tool's style/appearance. More at Custom themes

bauh_env/bin/pip install bauh  # installs bauh in the isolated environment
bauh_env/bin/bauh              # launches bauh. For the tray-mode: bauh_env/bin/bauh-tray

Updating bauh

bauh_env/bin/pip install bauh --upgrade

Uninstalling bauh

bauh_env/bin/bauh --reset  # removes cache and configurations files from HOME
rm -rf bauh_env` (just remove the directory)

Desktop entry / menu shortcut

To create a shortcut for bauh on your desktop menu:

  • Copy the files from bauh/desktop to ~/.local/share/applications (or /usr/share/applications for root)
  • Replace the Exec field on theses files by the bauh binary path. e.g: Exec=/usr/bin/bauh (or bauh_env/bin/bauh)
  • Copy logo.svg to /usr/share/icons/hicolor/scalable/apps as bauh.svg

Autostart: tray mode

In order to initialize bauh with the system, use your Desktop Environment settings to register it as a startup application / script (bauh-tray). Or create a file named bauh.desktop in ~/.config/autostart with the content below:

[Desktop Entry]
Type=Application
Name=bauh (tray)
Exec=/path/to/bauh-tray

Distribution

bauh is officially distributed through PyPi and AUR (bauh / bauh-staging)

Supported types

AppImage
  • Supported sources: AppImageHub (applications with no releases published to GitHub are not available)

  • All available application names can be found at apps.txt

  • Only x86_64 AppImage files are available through the search mechanism at the moment

  • Crashes may happen during an AppImage installation if AppImageLauncher is installed. It is recommended to uninstall it and reboot your system before trying to install an application.

  • Extra actions

    • Install AppImage file: allows to install an external AppImage file
    • Upgrade file: allows to upgrade a manually installed AppImage file
    • Update database: manually synchronize the AppImage database
  • Installed applications are store at ~/.local/share/bauh/appimage/installed (or /usr/local/share/bauh/installed for root)

  • Desktop entries (menu shortcuts) of the installed applications are stored at ~/.local/share/applications (or /usr/share/applications for root). Name pattern: bauh_appimage_appname.desktop

  • Symlinks are created at ~/.local/bin (or /usr/local/bin for root). They have the same name of the application (if the name already exists, it will be created as 'app_name-appimage'. e.g: rpcs3-appimage)

  • Downloaded database files are stored at ~/.cache/bauh/appimage (or /var/cache/bauh/appimage for root) as apps.db and releases.db

  • Databases are updated during the initialization process if they are considered outdated

  • The configuration file is located at ~/.config/bauh/appimage.yml (or /etc/bauh/appimage.yml for root) and it allows the following customizations:

  • Applications with ignored updates are defined at ~/.config/bauh/appimage/updates_ignored.txt (or /etc/bauh/appimage/updates_ignored.txt for root)

database:
  expiration: 60  # defines the period (in minutes) in which the database will be considered up to date during the initialization process. Use 0 if you always want to update it. Default: 60.
suggestions:
    expiration: 24  # defines the period (in hours) in which the suggestions stored in disc will be considered up to date. Use 0 if you always want to update them. Default: 24.
Arch packages/AUR
  • Only available for Arch-based systems

  • It handles conflicts, missing / optional packages installations, and several providers scenarios

  • rebuild-detector integration (AUR only)

  • Automatically makes simple package compilation improvements (for AUR packages):

    a) if MAKEFLAGS is not set in /etc/makepkg.conf, then a copy of /etc/makepkg.conf will be generated at ~/.config/bauh/arch/makepkg.conf defining MAKEFLAGS to work with the number of your machine processors (-j${nproc}).

    b) same as previous, but related to COMPRESSXZ and COMPRESSZST definitions (if '--threads=0' is not defined)

    c) ccache will be added to BUILDENV if it is installed on the system and already not defined

    d) set the device CPUs to performance scaling governor

    Obs: For more information about them, have a look at Makepkg

  • Extra actions

    • Synchronize packages database: synchronizes the database against the configured mirrors (sudo pacman -Syy)
    • Refresh mirrors: allows to define multiple mirrors locations and sort by the fastest (sudo pacman-mirrors -c country1,country2 && sudo pacman-mirrors --fasttrack 5 && sudo pacman -Syy)
    • Quick system upgrade: it executes a default pacman upgrade (pacman -Syyu --noconfirm)
    • Clean cache: it cleans the pacman cache directory (default: /var/cache/pacman/pkg)
    • Mark PKGBUILD as editable: it marks a given PKGBUILD of a package as editable (a popup with the PKGBUILD will be displayed before upgrading/downgrading this package). Action only available when the configuration property edit_aur_pkgbuild is not false.
    • Unmark PKGBUILD as editable: reverts the action described above. Action only available when the configuration property edit_aur_pkgbuild is not false.
    • Allow reinstallation check: it allows to check if a given AUR packages requires to be rebuilt
    • Ignore reinstallation check: it does not to check if a given AUR packages requires to be rebuilt
    • Check Snaps support: checks if the Snapd services are properly enabled.
    • Reinstall (AUR only): rebuilds an installed package.
  • If you have AUR added as a repository on you pacman configuration, make sure to disable bauh's support (through the settings described below)

  • AUR package compilation may require additional installed packages to work properly. Some of them are defined on the field optdepends of the PKGBUILD

  • Repository packages currently do not support the following actions: Downgrade and History

  • If some of your installed packages are not categorized, open a PullRequest to the bauh-files repository changing categories.txt

  • During bauh initialization a full AUR normalized index is saved at ~/.cache/bauh/arch/aur/index.txt

  • Installed AUR packages have their PKGBUILD files cached at ~/.cache/bauh/arch/installed/$pkgname

  • Packages with ignored updates are defined at ~/.config/bauh/arch/updates_ignored.txt

  • The configuration file is located at ~/.config/bauh/arch.yml and it allows the following customizations:

aur:  true # allows to manage AUR packages. Default: true

optimize: true  # if 'false': disables the auto-compilation improvements (AUR)
sync_databases: true # package databases synchronization once a day before the first package installation/upgrade/downgrade
sync_databases_startup: true  # package databases synchronization once a day during startup
clean_cached: true  # defines if old cached versions should be removed from the disk cache during a package uninstallation
refresh_mirrors_startup: false # if the package mirrors should be refreshed during startup
mirrors_sort_limit: 5  # defines the maximum number of mirrors that will be used for speed sorting. Use 0 for no limit or leave it blank to disable sorting. 
repositories_mthread_download: false  # enable multi-threaded download for repository packages if aria2/axel is installed (otherwise pacman will download the packages). Default: false
automatch_providers: true  # if a possible provider for a given package dependency exactly matches its name, it will be chosen instead of asking for the user to decide (false). Default: true.
edit_aur_pkgbuild: false  # if the AUR PKGBUILD file should be displayed for edition before the make process. true (PKGBUILD will always be displayed for edition), false (PKGBUILD never will be displayed), null (a popup will ask if the user want to edit the PKGBUILD). Default: false.
aur_build_dir: null  # defines a custom build directory for AUR packages (a null value will point to /tmp/bauh/arch (non-root user) or /tmp/bauh_root/arch (root user)). Default: null.
aur_remove_build_dir: true  # it defines if a package's generated build directory should be removed after the operation is finished (installation, upgrading, ...). Options: true, false (default: true).
aur_build_only_chosen : true  # some AUR packages have a common file definition declaring several packages to be built. When this property is 'true' only the package the user select to install will be built (unless its name is different from those declared in the PKGBUILD base). With a 'null' value a popup asking if the user wants to build all of them will be displayed. 'false' will build and install all packages. Default: true.
aur_idx_exp: 1  # It defines the period (in HOURS) for the AUR index stored in disc to be considered up to date during the initialization process. Use 0 so that it is always updated. Default: 1. (P.S: this index is always updated when a package is installed/upgraded)
check_dependency_breakage: true # if, during the verification of the update requirements, specific versions of dependencies must also be checked. Example: package A depends on version 1.0 of B. If A and B were selected to upgrade, and B would be upgrade to 2.0, then B would be excluded from the transaction. Default: true.
suggest_unneeded_uninstall: false  # if the dependencies apparently no longer necessary associated with the uninstalled packages should be suggested for uninstallation. When this property is enabled it automatically disables the property 'suggest_optdep_uninstall'. Default: false (to prevent new users from making mistakes)
suggest_optdep_uninstall: false  # if the optional dependencies associated with uninstalled packages should be suggested for uninstallation. Only the optional dependencies that are not dependencies of other packages will be suggested. Default: false (to prevent new users from making mistakes)
categories_exp: 24  # It defines the expiration time (in HOURS) of the packages categories mapping file stored in disc. Use 0 so that it is always updated during initialization.

Flatpak
  • Applications with ignored updates are defined at ~/.config/bauh/flatpak/updates_ignored.txt
  • The configuration file is located at ~/.config/bauh/flatpak.yml and it allows the following customizations:
installation_level: null # defines a default installation level: "user" or "system". (null will display a popup asking the level)

Snap

  • Make sure snapd is properly installed and enabled on your system: https://snapcraft.io/docs/installing-snapd
  • Extra actions:
    • Refresh: tries to update the current Snap application revision
    • Change channel: allows to change the Snap application channel
  • The configuration file is located at ~/.config/bauh/snap.yml and it allows the following customizations:
install_channel: false  # it allows to select an available channel during the application installation. Default: false

Native Web applications

  • It allows the installation of Web applications by typing their addresses/URLs on the search bar

  • It offers the possibility to customize the generated app the way you want:

  • It provides some suggestions coming with predefined settings, and they also can be found by their names. They are defined at suggestions.yml, and downloaded during the application usage.

  • It relies on NodeJS, Electron and nativefier to do all the magic, but you do not need them installed on your system. An isolated installation environment will be generated at ~/.local/share/bauh/web/env (or /usr/local/share/bauh/web/env for root).
  • It supports DRM protected content through a custom Electron implementation provided by castLabs. nativefier handles the switch between the official Electron and the custom.
  • The isolated environment is created based on the settings defined in environment.yml (downloaded during runtime).
  • Some applications require Javascript fixes to properly work. If there is a known fix, bauh will download the file from fix and attach it to the generated app.
  • The installed applications are located at ~/.local/share/bauh/installed (or /usr/local/share/bauh/web/installed for root).
  • A desktop entry / menu shortcut will be generated for the installed applications at ~/.local/share/applications (or /usr/share/applications for root)
  • If the Tray Mode Start Minimized is defined during the installation setup, a desktop entry will be also generated at ~/.config/autostart (or /etc/xdg/autostart for root) allowing the application to launch automatically after the system's boot attached to the tray.

  • Extra actions

    • Clean installation environment: removes all the installation environment folders (it does not remove installed apps)
  • The configuration file is located at ~/.config/bauh/web.yml (or /etc/bauh/web.yml for root) and it allows the following customizations:

environment:
  electron:
    version: null  # set a custom Electron version here (e.g: '6.1.4')
  system: false  # set it to 'true' if you want to use the nativefier version globally installed on your system 
  cache_exp: 24 # defines the period (in HOURS) in which the stored environment settings are considered valid. Use 0 so that they are always updated. Default: 24.

suggestions:
    cache_exp: 24  # defines the period (in HOURS) in which suggestions stored on the disk are considered up to date during the initialization process. Use 0 so that they are always updated. Default: 24.

Directory structure, caching and logs

  • ~/.config/bauh (or /etc/bauh for root): stores configuration files
  • ~/.cache/bauh (or /var/cache/bauh for root): stores data about your installed applications, databases, indexes, etc. Files are stored here to provide a faster initialization and data recovery.
  • /tmp/bauh@$USER (e.g: /tmp/bauh@root): stores logging and temporary files (e.g: build dependencies)

Custom themes

  • Custom themes can be provided by adding their files at ~/.local/share/bauh/themes (or /usr/share/bauh/themes for root). Sub-folders are allowed.
  • Themes are composed by 2 required and 1 optional files sharing the same name:
    • my_theme.qss: file with the qss rules. Full example: light.qss
    • my_theme.meta: file defining the theme's data. Full example: light.meta
      • available fields:
        • name: name that will be displayed on the interface. It supports translations by adding additional name fields with brackets and the language code (e.g: name[es]=Mi tema)
        • description: theme's description that will be displayed on the interface. It supports translations like name (e.g: description[es] = Mi tema).
        • version: theme's version. It just works as information at the moment. (e.g: 1.0)
        • root_theme: optional attribute that points to a theme that must be loaded before the theme. It supports the bauh's default theme keys (e.g: default, light, ...) or a file path (e.g: /path/to/root/file.qss).
        • abstract: optional boolean attribute (true/false) that should only be used by themes that are not complete on their own and just work as a base (root) for other themes. Abstract themes are not displayed on the interface. Full example: default.qss
    • my_theme.vars: optional file defining key=value pairs of variables that will be available for the .qss file (can be referenced through the symbol @. e.g @my_var). Full example: light.vars
      • common theme variables available:
        • style_dir: path to the .qss file directory. Example: @style_dir/my_icon.svg
        • images: path to bauh's icons directory (gem icons are not available through this variable). Example: @images/logo.svg

Tray icons

Priority:

  1. Icon paths defined in ~/.config/bauh/config.yml
  2. Icons from the system with the following names: bauh_tray_default and bauh_tray_updates
  3. Own packaged icons

CLI (Command Line Interface)

  • For now it only allows checking for software updates (bauh-cli updates).
  • To verify the available commands: bauh-cli --help.
  • To list the command parameters: bauh-cli [command] --help. (e.g: bauh-cli updates --help)

Improving performance

  • Disable the application types you do not want to deal with
  • If you don't care about restarting the app every time a new supported package technology is installed, enable single_dependency_checking. This can reduce the application response time, since it won't need to recheck if the required technologies are available on your system every time a given action is executed.
  • If you don't mind to see the applications icons, you can disable them via download: icons: false. The application may have a slight response improvement, since it will reduce the IO and parallelism within it.
  • For a faster initialization process, consider raising the values of the settings properties associated with disk caching and the property boot.load_apps to false.

bauh-files

It is a separate repository with some files downloaded during runtime.

Code structure

  • view: code associated with the graphical interface
  • gems: code responsible to work with the different packaging technologies (every submodule deals with one or more types)
  • api: code abstractions representing the main actions that a user can do with Linux packages (search, install, ...). These abstractions are implemented by the gems, and the view code is only attached to them (it does not know how the gems handle these actions)
  • commons: common code used by gems and view

Roadmap

  • Support for other packaging technologies
  • Separate modules for each packaging technology
  • Memory and performance improvements
  • Improve user experience
