Broken dependency, unable to update or install packages

Asked by Luther

When using apt-get install:

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 python3 : Depends: python3-minimal (= 3.2.3-5ubuntu1) but 3.2.3-5ubuntu1.1 is to be installed
 python3-dev : Depends: python3 (= 3.2.3-5ubuntu1.1) but 3.2.3-5ubuntu1 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

It looks like the '=' should be '>='. If I run 'apt-get -f install', it tries to uninstall a very large number of packages.

Please provide the output of

apt-cache policy python3 python3-minimal python3-dev

Errors like the one that you experience can among others be caused by enabling the -proposed repository or a PPA, installing/upgrading programs, disabling -proposed or a PPA, and trying installs or upgrades again.
Have you done any removal from the list of your sources recently?

Can you help with this problem?

Provide an answer of your own, or ask Luther for more information if necessary.
