Check Package Version
apt-cache
The option
policy can show the installed and the remote version (install candidate) of a package.apt-cache policy <package>
You can run a simulation to see what would happen if you upgrade/install a package:
apt-get -s install <package>
To see all possible upgrades, run a
upgrade in verbose mode and (to be safe) with simulation, press n to cancel:apt-get -V -s upgrade
apt-show-versions
If installed, shows version information about one or more packages:
apt-show-versions <package>
Passing the
-u switch with or without a package name will only show upgradeable packages.aptitude
The console GUI of
aptitude can display upgradeable packages with new versions. Open the menu Upgradable Packages. Pressing v on a package will show more detailed version information.Or on the command-line:
aptitude versions <package>
Passing
-V will show detailed information about versions, again to be safe with the simulation switch:aptitude -V -s install <package>
Substituting
install <package> with upgrade will show the versions from all upgradeable packages.
