Thanks for that. But now I get: The following packages have unmet dependencies: mp-fremantle-generic-pr: Depends: perl-base (= 5.8.3-3osso10) but 5.8.3-3osso11+0m5 is to be installed E: Broken packages What should I do, remove and install perl-base? When I intend to do that, apt wants to wipe out half of the system. So what can I do?
