Chromium's sandbox won't work inside flatpak's sandbox because it's a setuid binary, so reflect the README not to lead to misunderstandings

Compilation of resources to try to build chromium-browser as an flatpak application.

WARNING: This is WORK-IN-PROGRESS and it's not guaranteed to work (it just builds for now), any comments are welcome.

Requirements:

  • flatpak >= 0.5
  • flatpak-builder >= 0.5
  • appstream-composer (automatically run by flatpak-builder)
  • org.gnome Platform and Sdk runtimes

Instructions:

(1) Install the flatpak repository for GNOME nightly:

  wget http://sdk.gnome.org/nightly/keys/nightly.gpg
  flatpak --user remote-add --gpg-import=nightly.gpg gnome-nightly http://sdk.gnome.org/nightly/repo

(2) Install the required runtimes

  flatpak --user install gnome-nightly org.gnome.Platform
  flatpak --user install gnome-nightly org.gnome.Sdk

(3) Build chromium-browser) From this directory:

  flatpak-builder --repo=/path/to/your/flatpak/repo \
    /path/to/flatpak/appdir \
    org.chromium.ChromiumBrowser

(4) Add a remote to your local repo and install it:

  flatpak --user remote-add --no-gpg-verify chromium-repo /path/to/your/flatpak/repo
  flatpak --user install chromium-repo org.chromium.ChromiumBrowser

(5) Run chromium-browser as an flatpak (needs to disable chromium's sandbox because a setuid binary won't work in flatpak):

  flatpak run org.chromium.ChromiumBrowser --no-sandbox

Note that if you do further changes in the appdir (e.g. to the metadata), you'll need to re-publish it in your local repo and update before running it again:

  flatpak build-export /path/to/your/flatpak/repo /path/to/flatpak/appdir
  flatpak --user update org.chromium.ChromiumBrowser

Last, you can bundle chromium to a file with the build-bundle subcommand:

  flatpak build-bundle /path/to/your/flatpak/repo chromium-browser.bundle org.chromium.ChromiumBrowser
