[Bug 1850908] Re: Upgrade from 18.04 to 18.10 didn't work, neither the upgrade to 19.10. Created a new usb drive with 19.10. It detects that there is a 19.10, but was not able to reinstall

[Chris Guiver]

Thank you for taking the time to report this bug and helping to make
Ubuntu better.

Ubuntu 18.10 reached EOL on July 18, 2019.  That closed the door to
upgrades from 18.04 LTS, so that was expected
(http://fridge.ubuntu.com/2019/07/19/ubuntu-18-10-cosmic-cuttlefish-end-
of-life-reached-on-july-18-2019/)

Ubuntu 18.04 LTS has two supported & tested upgrade paths, one was to
18.10 (now closed), the other will be to Ubuntu 20.04 (once Ubuntu
20.04.1 has been released).

This installation looks like it was caused by a corrupted file system. I
notice in the logs

Nov  1 09:33:46 ubuntu kernel: [  357.600900] EXT4-fs error (device sda4): ext4_mb_generate_buddy:744: group 198, block bitmap and bg descriptor inconsistent: 1082 vs 1086 free clusters

I've marked this bug as incomplete, and suggest you `fsck` (file system
check) your partition to fix errors, and try again. If you believe I'm
in error please leave a comment as to why, and you can return the status
to "New".

If you are unfamiliar with `fsck` (or file system checks) please refer
to https://help.ubuntu.com/community/FilesystemTroubleshooting or for
actual help please refer to https://discourse.ubuntu.com/t/finding-
help/712
