I missed menu.lst mentioned before. This is a grub1 file and even for a 32bit (i386) installation I would have thought everything already migrated to use grub2. The only thing which I thought were still using menu.lst were paravirt Xen guests on the Amazon cloud. There was some pain with grub1 and menu.lst related to configuration questions (do you want to keep the current version or install a new one). Answering keep there would any future update and basically keep people from using any updated kernel.
But to the problem, if changing menu.lst helped to switch back to the previous kernel, then you are still using grub1. So the lines in there for 43 and the 45 kernel should look the same (except version numbers). Does manually running "sudo update-grub" fix this? I don't think there is a update-grub-legacy-ec2 around (that would probably only be there when using grub2) but if it is there, that normally can be used to force menu.lst to be comparable to what grub.cfg contains. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1814830 Title: recent linux versions 44 and 45 do not start up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1814830/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
