I know there a lot of such question were asked, but no one answer helped me.
Here is an error I beat with for few hours already.
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
cmake : Depends: libcurl3 (>= 7.16.2) but it is not installable

I tried apt-get clean and sudo apt --fix-broken install - nothing helped me. I tried comment out repositories in source.list one by one and run apt-get update && apt-get upgrade but get the same error.
If I'll run sudo apt-get install -f or sudo apt --fix-broken install one more error messeage starts appear in console
E: Error, pkgProblemResolver::Resolve generated breaks, this may be cause by help packages
Running sudo dpkg --get-selections | grep hold shows nothing.
Any ideas?
