Requirements

apt-cyg requires the Cygwin default environment and the additional Cygwin packages:

wget, ca-certificates, gnupg, libiconv

In 32bit version of cygwin, wget requires an additional setting for the ca-certificates package. Choose one of below settings.

# 1. Create symbolic link for the default ca-directory of wget. 
ln -s /usr/ssl /etc/

# or
# 2. Set ca-directory paramete in '/etc/wgetrc'. 
echo "ca-directory = /usr/ssl/certs" >> /etc/wgetrc

# or
# 3. Set ca-directory paramete in '~/.wgetrc'. 
echo "ca-directory = /usr/ssl/certs" >> ~/.wgetrc

Remarks: Above additional settings for wget is not required for 64bit version of cygwin. But, as of 2014-01-17, perhaps ca-certificates package makes fail of certification in 64bit version of cygwin with Windows 8. See below:

Known Problem / 2014-01-17: ca-certificates package is not setup correct at x86_64 with Windows 8.

Quick start

The most recommended way to deploy this fork can be seen from a link below:

New features / Upgrade apt-cyg

apt-cyg is a simple script. Once you have a copy, make it executable:

chmod +x /bin/apt-cyg

Optionally place apt-cyg in a bin/ folder on your path.

Then use apt-cyg, for example:

apt-cyg install nano

New features

dist-upgrade support

This fork has achieved dist-upgrade command by using setup-x86.exe and setup-x86_64.exe as a backend. Note that all of running tasks on the cygwin will be killed before starting dist-upgrade.

Multiple hash algorithms support

After the middle of 2015-03, the cygwin project changed the hash algorithm for checking tarball from md5 to sha512. But, as of 2015-04-09, the cygwinports project seems still using md5. This fork is available for both of cygwin and cygwinports by supporting algorithm of md5, sha1, sha224, sha256 and sha512.

Signature check and key management by GnuPG

The default action of apt-cyg has been changed to check signature for 'setup.ini'. Of course you can also avoid signature check by using --no-verify or -X options. Public keys of cygwin and cygwinports are already registered to trusted keys of embeded. If you want to use some other public keys, please use key-* subcommands.

Upgrade apt-cyg

If apt-cyg is under Git version control, this fork can upgrade itself by upgrade-self subcommand. Therefore, the most recommended way to deploy this fork is copy and paste below commands to cygwin console:

# cd $DIR # Change working directory where you want to install apt-cyg
git clone https://github.com/kou1okada/apt-cyg.git
ln -s "$(realpath apt-cyg/apt-cyg)" /usr/local/bin/

If you want to use another fork, which forked from https://github.com/kou1okada/apt-cyg, rewrite the URL for apropriate one.

Proxy support

Use --proxy, -p option. This option must take a parameter from one of "auto", "inherit", "none" and URL.

"auto" will determine a proxy using a part of the Web Proxy Auto-Discovery Protocol (WPAD). The current implementation will look for a string of "PROXY URL" from "http://wpad/wpad.dat". If "wpad.dat" could not be downloaded, the proxy settings are inherited from the parent environment.
"inherit" will inherit the proxy settings from the parent environment.
"none" will not use the proxy.
URL can take a string like "protocol://hostname:port".

For example:

apt-cyg --proxy http://proxy.home:8080 update

The default parameter is "${APT_CYG_PROXY:-auto}". At the environment where is not provided the WPAD server, it makes the lag for a few seconds at startup. So, if you don't want to use WPAD, please define APT_CYG_PROXY environment variable as below:

export APT_CYG_PROXY=inherit

Bash completion support

Bash completion script can be installed to "/etc/bash_completion.d/apt-cyg" by completion-install subcommand. It will be automatically updated when apt-cyg is upgraded to newer version. If you don't want to update it automatically, execute completion-install subcommand in conjunction with --completion-disable-autoupdate option. And completion-uninstall subcommand removes "/etc/bash_completion.d/apt-cyg".

Some other forks, Milly / apt-cyg under the cfg / apt-cyg fork, ashumkin / apt-cyg and etc, are also supported it.

Caution: Please do not merge forks that have incompatible licenses.

Ex.) Merging to the GPL from the MIT is possible. But merging to the MIT from the GPL is impossible.

Todo

Support multi mirrors: Cygwin setup can use multi mirrors. They are recorded at last-mirror section in '/etc/setup/setup.rc'. It's useful for using Cygwinports.
Support upgrade: But maybe, busy resources can not be upgraded, and rebase problem will happen. Cygwin setup resolves by replacing them at next reboot.
Support dependency check for remove subcommand.
