Can I go back to a non-backports version of my
I still want ultimately to have the latest version of Digikam but
revert everthing else, including Amarok to version 1.4 again.
Is it a matter of disabling the backport repo and doing 'sudo apt-get upgrade' ?
It's not that simple, because you'll have installed newer versions of
the packages than are available in the standard repo. apt-get upgrade
(or any variant on that) will not upgrade packages to "older" packages
just because you don't have a valid repo for them
The most straightforward way of fixing it is to reinstall. You could use
apt-cache policy and iterate over all your packages, working out which
came from backports and which from the normal repos, then manually
downgrade all those packages, but it'll take a fair while to do if
you've pulled in all of KDE.
In general, you should use pinning when using a backport, to make sure
that you don't inadvertently pull in lots of unwanted packages.
