apt-cyg

apt-cyg is a command-line installer for Cygwin which cooperates with Cygwin Setup and uses the same repository. The syntax is similar to apt-get. Usage examples:

"apt-cyg install <package names>" to install packages
"apt-cyg remove <package names>" to remove packages
"apt-cyg update" to update setup.ini
"apt-cyg show" to show installed packages
"apt-cyg find <pattern(s)>" to find packages matching patterns
"apt-cyg describe <pattern(s)>" to describe packages matching patterns
"apt-cyg packageof <commands or files>" to locate parent packages
"apt-cyg pathof <cache|mirror|mirrordir|cache/mirrordir>" to show path"
"apt-cyg key-add <files> ..." to add keys contained in <files>
"apt-cyg key-del <keyids> ..." to remove keys <keyids>
"apt-cyg key-list" to list keys
"apt-cyg key-finger" to list fingerprints

Requirements

apt-cyg requires the cygwin default environment and optional packages below.

wget,ca-certificates,gnupg

In 32bit version of cygwin, wget requires an additional setting for 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

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

True multi-architecture support

Let think a case that you want to install the x86 package when you are working under the x86_64 environment. For example:

# apt-cyg --charch x86 install chere

As of 2013-10-26, chere package is provided for only the repository for x86.

Remarks: Of course, you must install both environments of x86_64 and x86, beforehand.

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.

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 completion: Some other forks already supported it. For example, Milly / apt-cyg under the cfg / apt-cyg fork, ashumkin / apt-cyg and etc supported it.
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.

Known Problem

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

After clean installing with setup-x86_64, there are something wrong about ca-certificate package as below:

$ ls -lnG \
     /cygdrive/c/cygwin/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt \
     /cygdrive/c/cygwin64/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt
-r--r--r-- 1 1001 314336 Jan 17 18:17 /cygdrive/c/cygwin/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt
-rw-r--r-- 1 1001      0 Oct 16 12:35 /cygdrive/c/cygwin64/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt
$ ls -lnG \
     /cygdrive/c/cygwin/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem \
     /cygdrive/c/cygwin64/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
-r--r--r-- 1 1001 232342 Jan 17 18:17 /cygdrive/c/cygwin/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
-rw-r--r-- 1 1001      0 Oct 16 12:35 /cygdrive/c/cygwin64/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem

The x86 environment seems no problem except that need an additional setting for wget and ca-certificate. Hmm,,,

It seems that /usr/bin/update-ca-trust is failed at x86_64.

It's ad hoc, but effective way to fix it, is to copy files from cygwin32 to cygwin64, as below:

cp -a /cygdrive/c/cygwin/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt \
      /cygdrive/c/cygwin64/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt
cp -a /cygdrive/c/cygwin/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem \
      /cygdrive/c/cygwin64/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem

This problem is fixed at 2014-01-24. version 0.18.7-1 of p11-kit, p11-kit-trust and libp11-kit0 did not work at the cygwin64 under the Windows 8. If you face the above problem, please upgrade these three packages from version 0.18.7-1 to version 0.18.7-2.

For more details, see a thread of below:

Cygwin mailing list / cygwin / Re: Is there someone who have a same problem ?

2014-01-15: Signature check failed at cygwinports x86_64.

Oops, setup.bz2 is newer than setup.bz2.sig. And it seems to be corrupted.

You can use the `bzip2recover' program to attempt to recover

As of 2014-01-24, above problem is recovered at least.

FIXED: Check setup (cygcheck -c) can not detect .tar.xz packages

At cygwin 1.7.25, cygcheck is hardcoded for .tar.gz and .tar.bz2. So check setup (cygcheck -c) can not detect .tar.xz packages. This bug was already fixed with src/winsup/utils/dump_setup.cc#rev1.28. Please wait a release of cygwin 1.7.26.

This Problem was fixed cygwin 1.7.26 which released at 2013-11-29.
