You can upgrade all installed packages with:
$ wajig upgrade (apt-get -u upgrade)
|
And you can upgrade all installed packages, remove those packages that
need to be removed (for various reasons, including issues to do with
dependencies) and install all newly required packages in the
distribution with:
$ wajig dist-upgrade (apt-get -u dist-upgrade)
|
Note that a dist-upgrade will potentially remove packages
where dependency checking indicates this is necessary. Important
packages (determined by the Priority specification which can
be found using the details command) will be upgraded even at
the cost of downgrading other (less important) packages.
If this is an issue for you then you should use the
upgrade command rather than dist-upgrade. This
command will never remove or downgrade a package.
To upgrade to a specific distribution (e.g., experimental) you can
use:
$ wajig dist-upgrade experimental
|
Note that the mentioned distribution must also be mentioned in your
/etc/apt/sources.list file.
A neat trick with wajig is the ability to upgrade
a collection of packages all with the same version number to another
common version number:
$ wajig status | grep 3.2.3-2 | grep 3.3.0-1 | cut -f1 > list
$ wajig install-file list
