I'm new to Ubuntu. I'm running 18.04 LTS and a few weeks ago unfortunately I ran into a bad kernel bug by accidentally downloading it via updater.

That time I simply confirmed everything that came in as suggested update. After this a reboot was not possible anymore and I had to do many things to get the system back up and running.

Now the updater again reports many new features and updates coming in. I definitely don't want to go through a new kernel update again. How do I know which modules I can select for download that the system is working again after reboot?

Thanks for your help!

  • I recall an issue like what you describe due to a software bug; which was just bad luck for the very-few that were effected by it. Once it was reported (via launchpad), it was soon fixed, but would still have been annoying for anyone affected. You could limit yourself to apt upgrade (rather than dist-upgrade or full-upgrade), but you'd also become more vulnerable to security-flaws as you'd not be getting all updates which wouldn't be wise depending on your use case. – guiverc Aug 31 '18 at 09:30
  • Thank you! Is there an option to check on the GUI Software updater as well? (I mean apt upgrade instead if dist-upgrade or full-upgrade) – ssssstut Aug 31 '18 at 09:44
  • For future issues with kernel: you can pick the old kernel during booting when grub shows up. – Rinzwind Aug 31 '18 at 10:08

    @guiverc maybe this: https://askubuntu.com/questions/1052159/why-did-bionic-kernel-update-to-4-15-0-24-get-removed-from-the-repos ? Also worth mentioning is that that using the GUI with Ubuntu's software manager may afford phased updates (and so some extent of safety). – DK Bose Aug 31 '18 at 10:34
  • @DKBose if it can be done via GUI, someone else (you?) will need to answer. Alas I'm only familiar with terminal; unsuitable for this OP or answer... – guiverc Aug 31 '18 at 10:42
  • Set your update policy to every two weeks. Check here if other Ubuntu 18.04 users have had problems with recent updates before you apply yours. Use 16.04 instead for a couple of years until 18.04 development cycle slows down. Just a few thoughts, not the answer you seek. – WinEunuuchs2Unix Aug 31 '18 at 11:01
