Public bug reported: I have recently installed 15.10 on three systems. In one case, it was a semi-fresh install, over top of an existing 15.04 install that had been a failed upgrade from 14.10 LTS. In the other two cases, they were successful upgrades from 15.04.
In all three cases, the kernel did not get upgraded with the rest of the OS, so I had to manually run this: sudo apt-get install linux-generic Only then did I get the right kernel. And only then could I get things like nfs-server to work, so the failure to upgrade the kernel causes all sorts of other problems, because a lot of other packages are dependent on having the right kernel. I'm not the only person to notice this. I found the fix from this forum post: http://askubuntu.com/questions/689358/ubuntu-kernel-not-updating-with-15-10 ** Affects: ubuntu-release-upgrader (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1510325 Title: 15.10 upgrade doesn't upgrade kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1510325/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
