There is no need for me to attach my main.log since it is identical to all main.log files posted here already. There is an obvious problem with this upgrade. I'm struggling with it the third day and no solution found so far. OK!... Right now when I'm writing I have a little change to positive in Update Manager behavior. It finally get prerequisites and looks like it is proceeding further on. To get to this point I had to disable "universe"/"community supported" in my sources list. I was prompted that some of packages installed on my PC are no longer supported by Canonical and I would be prompted to remove them after upgrade completed or I would be able to choose keeping them if I wish. Right now I am in the 3-d step - Fetching the Upgrades. Let's hope this was a solution. I think if the Upgrade process is so picky to what is currently supported by Canonical and what is not then the procedure should have started from backing up a local sources.list file, replacing it with one that can for sure satisfy the Upgrade and then to proceed with the upgrade. Then after the Upgrade is completed a user could be prompted about changes in files support by Canonical and be given a choice either to use a new sources.list or to get back to his own one. Otherwise the Upgrade is a nightmare. It was much easier for me just to install it fresh. -- [update-manager] Getting upgrade prerequisites failed https://bugs.launchpad.net/bugs/154008 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
