Have been trying to fix it in various ways, but all these advices on the internet turned out useless for me. It was too strange to see when one instruction help other people, but don't solve my problem.
When I mark the package in Synaptic Package Manager and press "Apply", it says:
Could not apply changes! Fix broken packages first.
Then i click Synaptic --> Edit --> Fix Broken Packages and i get this:
An error occurred The following details are provided: E: Unable to correct problems, you have held broken packages. E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. E: Unable to correct dependencies
Is there any way to fix this issue?
