  • Yeah, I use it a fair bit, although I do have admin rights. Don't think they should be necessary after install though.

  • Cheers. Maybe I'll test it out on a home machine before trying to get someone in IT who doesn't know anything about it to set it up.

  • I'm not sure how to ask my question (which is why I've struggled to solve it), but I think I am asking how to edit the boot sequence to load a previous kernel due to an issue with my current one.

    Laptop won't boot directly to the OS/fails, so it tells me to hit enter to go into grub(?), where it presents a list of kernels(?) - ie

    • Ubuntu 18.04.2 LTS, kernel 4.15.0-52-generic
    • Ubuntu 18.04.2 LTS, kernel 4.15.0-52-generic (recovery mode)
    • Ubuntu 18.04.2 LTS, kernel 4.15.0-51-generic
    • Ubuntu 18.04.2 LTS, kernel 4.15.0-51-generic (recovery mode)
      -...and so on

    If I select …0-52 or …0-52 recovery it fails.
    If I select …0-51 it loads.
    What do I do to revert back to 0-51 / or boot directly to it ?


  • When I had this issue I deleted the newer kernel and it seemed to fall back to the previous kernel and that worked fine.

    I probably followed something along these lines­ow-to-delete-a-non-working-kernel-after-­update but I'm no expert so you may want to wait for someone else who doesn't just do stuff by trial and error to weigh in.

  • You should be able to remove the defunct entries with GRUB Customizer. I've used it to change the default boot order and it works well

  • Cheers folks!

    Will give those a try.
