The default behavior is to update_cache if changed.
If you add more then one repo, you may not want to update cache for every repo separately.
So you can now disable update_cache with this new option e.g. update_cache=no
Updating cache can also be handled using the apt module.
Packages which are half-installed are not adequately represented by
the .is_installed field of the apt.package.Package object. By using the
lower-level apt_pkg.Package object (which provides the .current_state
field), we can check for a partially-installed state more accurately.
Fixes#3421
Without this, the first call to the easy_install module with a new virtualenv
will only create the virtualenv without installing the intended package, since
the `_is_package_installed` check will succeed as running /usr/bin/easy_install
as non-root user will return permission denied error with empty stdout.
Yum commandline permit to use a wildcard to enable and disable
repositories in the --enablerepo switch, permitting to enable
a complete set of repository at once ( like all rpmfusion, all
update-testing, etc ).
However, this doesn't work in yum due to more stringent checks
that verify that a exact match is given for the name of the
repository , see commit 5c26805.
This commit enhance the check by permitting to test more than
1 repository at a time, thus permitting to use wildcards.
1. Debian Squeeze is supported out of box now.
2. Repository type "deb" or "deb-src" should be explicitly specified.
3. If a source had beed added it must be possible to remove it.
4. PPA can be only used against Ubuntu hosts.
I'm seeing ansible hang when trying to remove a package, and the hung
process is `whiptail` like in #2763. It looks like we only use
`APT_ENVVARS` and `DPKG_OPTIONS` for the `apt` commands in install()
and upgrade(). This change uses them in remove() as well, which fixes
the hang.
