I managed to break my package management. If I try to make an upgrade, I get:
$ sudo apt-get dist-upgrade Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt-get -f install' to correct these. The following packages have unmet dependencies: libapt-pkg4.12 : Breaks: libapt-pkg4.12:i386 (!= 0.8.16~exp12ubuntu10.3) but 0.8.16~exp12ubuntu10.2 is installed libapt-pkg4.12:i386 : Breaks: libapt-pkg4.12 (!= 0.8.16~exp12ubuntu10.2) but 0.8.16~exp12ubuntu10.3 is installed E: Unmet dependencies. Try using -f.
Then I try to follow apt-get recommendation:
$ sudo apt-get -f install Reading package lists... Done Building dependency tree Reading state information... Done Correcting dependencies... Done The following packages will be REMOVED: libapt-inst1.4:i386 libapt-pkg4.12:i386 0 upgraded, 0 newly installed, 2 to remove and 33 not upgraded. 48 not fully installed or removed. After this operation, 3 866 kB disk space will be freed. Do you want to continue [Y/n]? E: Internal Error, No file name for libapt-pkg4.12
Kubuntu 12.04 64bit. Can anyone help me to solve it?
