After Ubuntu 18.04.1 LTS upgrade, there were several problems: Xubuntu icons missing, broken dependencies, no more network manager...

Do you have any idea why it happened and is there a solution? I cannot update packages anymore with apt-get and aptitude asks me to "try harder".

I cannot believe that so much problems can happen with a stable LTS upgrade. If I can't find a proper solution, I will have to replace Ubuntu with Debian or another Linux distribution. A few years ago, I switched from Unity interface to Xubuntu to avoid some annoying bugs: (it looks like my question was removed without any reason which was not nice for an open community Q&A website where closing would be enough and better to keep archives for users)

Ubuntu upgrade problems Ubuntu aptitude error

  • @user535733 it looks like my sources.list file and sources.list.d directory is fine, third-party packages are disabled (commented): But thanks for your suggestion, any other idea is welcome. – baptx Oct 21 at 14:45
  • I found some similar problems and tried this solution:… I am not sure it was the correct solution to my problem because in the end I had to use aptitude to purge broken dependencies (apt / apt-get command was not able to do it). So maybe the problem could have been fixed by just removing broken dependencies with aptitude. I still have no idea why this broken dependencies problem occurred. – baptx Oct 22 at 17:08
