    Help! Fedora upgrade failed to start. How to abandon upgrade?

    I tried to upgrade from 25 to 27. I get the message the upgrade fails to start then my laptop goes into a reboot.

    I can get into the recovery boot or get to my files with a live CD.

    I am no longer interested in trying to fix the upgrade. I would like to stick to 25. How do I cancel the upgrade and get my system back? Surely there is something pointing at the upgrade that I can delete?

    First things first, backup your files!

    Second, try selecting the older Kernel in the grub list, although that probably won't work.

    Then you could try a "dnf history list" to see a list of dnf transactions, get the ID of the update from the left column and then "dnf history rollback <ID>". However I'm not sure if it will work on a OS level upgrade.

    Lastly, and probably your best option is to reinstall from a live CD to make sure the system is clean. I assume all of your files are in a separate /home partition in which case it's just a matter of making sure you select not to format the /home partition when you select the disk layout.

    BTW, you should only upgrade one OS level at a time, so F25 -> F26 -> F27.

    Solved the problem.

    Years ago, due to space problems on / I had moved dnf from /var/lib to /home and put a link. I moved dnf back to /var/lib.

    When I rebooted I was back in fedora 25. No more mention of the upgrade from fedora.
