I am neither able to install nor remove any package through apt or dpkg. I don't have aptitude installed. Here are unmet dependecies on my ubuntu version - 12.04 precise:

It seems that my current required packages have somehow become dependent on old version of libc6-dev (2.15-0ubuntu10.12). How can I fix this? I have tried to follow some other related threads but have failed to fix it so far. Can someone please help?

Is aptitude smarter than apt-get or dpkg? – user1694519 Nov 02 '15 at 20:21aptitudeis more aggressive thanapt-get, which lets it fix more things (and break more things :p). Since it seems something got messed up, I would recommend trying it, but only after performing a backup. It might also be a good idea to go to 14.04, unless something is preventing that. – TheWanderer Nov 02 '15 at 20:23aptitude install -f– TheWanderer Nov 04 '15 at 19:28
