We have a 10 year old desktop PC that uses an AMD CPU. It is also the computer with the minimum of customizations. I assumed that it would be the easiest to upgrade. Well the upgrade failed. Apparently there was an issue with '
systemd-shim'. Please see:
systemd-shim error after upgrading from 16.04 to 16.10. If anyone knows of a better post concerning this issue, please provide a link so that others can be helped. Whether this issue will affect my other PCs is unknown.
Apparently, under Ubuntu 18.04, there is not an option to simply re-install the operating system (Ubuntu 18.04). However, there is an option to install Ubuntu 18.04 alongside the existing but failed install. I did that. It worked.
I was now "
stuck" with having to restore all my data files to new locations and deleting the failed installed, Since the computer is old (10 years) I looked into
Lubuntu as being an alternative to Ubuntu. Lubuntu has been installed and I am currently restoring the data files and doing other tweaks. See my post:
Lubuntu Won't Shutdown, Reboots - It's the Microcode Firmware for an unexpected problem.
The major point that I wish to make with the failure of Ubuntu to upgrade is to
clone the drive just before undertaking the upgrade. See
Clonzilla. That would have saved me a bunch of trouble. Perhaps, I could have resolved the issue with '
systemd-shim' and then tried to upgrade again.
Even-though, all my data-files were backed-up, cloning has an added advantage of restoring your system to its prior state following a failed upgrade.
