This question already has an answer here:
I was upgrading from Ubuntu 10.04 to Ubuntu 12.04 but my upgrade paused on
libc6-dev for around 2 hours. I rebooted my system and now I'm getting you have held broken packages. I've tried looking through other posts but none of the fixes seem to work for me and I just don't think I know enough to fix it myself.
In synaptic package manager I'm getting
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. E: Unable to correct dependencies
I'm unsure what to do in terminal to try and fix this. I seem to be working fine in 10.04 still but without fixing this I can't upgrade to 12.04.
