Public bug reported: I decided to test Ubuntu 18.04 on an old computer with 16.04 32-bit without knowing that only 64-bit was supported. do-release-upgrade seemed to perform all the actions without any problem. But, logically, the newly installed OS didn’t work.
After a quick research, I realised that the problem was the 32-/64-bit part and reinstalled the 16.04 32-bit version. I was forced to format the main partition as far as the 32-bit installer didn't recognise the 64-bit installation as a valid OS. After finishing the 16.04 32-bit installation, performing the recommended updates and installing just a few programs (very stable and which I have always used on that computer), the OS started behaving weirdly. At first sight, it was working fine, but kept getting regularly frozen and not starting properly. Finally, I seemed to have fixed all the problems by forcing (because it wasn't immediately available either) dist-upgrade. Long story short: my computer has been behaving erratically for 2 days without never getting a clear indication about what might be wrong. Even worse, all this has been provoked because the OS allowed me to perform an impossible action. The fix seems also quite straightforward: avoid any 32-bit version to be upgraded unless that format is available. ** Affects: ubuntu Importance: Undecided Status: New ** Tags: 18.04 32-bit bot-comment do-release-upgrade -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1769433 Title: do-release-upgrade from 32-bit 16.04 to 18.04 goes ahead, doesn't work and messes everything up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1769433/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
