A good practice is to keep all necessary system files on the boot disk and not depend on another disk to boot. Not always possible, I understand.
Check your BIOS for boot order. It may have tried to use the USB. Check if nfs is running to be sure after the upgrade. Just some suggestions. -- Cathy L.

At the Clinic today I tried to do a dist-upgrade from Xubuntu 16.04-6 to 18.04. After massive efforts we failed due to the Update Manager being unable to find files. When I got home I tried again, and this time the update sailed through without a single error. I made no changes to anything before doing this, so there is a question why the Update Manager could not find files from Free Geek, but had no problem from my home internet connection. But that is a discussion to leave for another day. However, although the dist-upgrade proceeded beautifully, when it ended the computer will not boot, that is, it will not boot to the GUI. It will only boot to a command line. There is an option 'systemctl-default' to view the logs and I perused them completely. No errors stood out except 'Subject: Unit dev-sdb2 device has failed; Unit home mount has failed.' On this computer /dev/sdb is a 512GB SSD with two partitions, / of 50GB and /home of 400GB (dev/sdb2). Of course, /home has tons of config files for software, so failing to boot the GUI without a /home folder is understandable. But why would the OS suddenly be unable to find /home? Any suggestions welcome! _______________________________________________ PLUG mailing list PLUG@pdxlinux.org https://protect2.fireeye.com/v1/url?k=4c61e10a-10d4dfc5-4c61cb1f-0cc47adc5e60-3f16e17efd23e534&q=1&e=ab83912e-0810-4717-b0bd-d2a550ddbbf9&u=http%3A%2F%2Flists.pdxlinux.org%2Fmailman%2Flistinfo%2Fplug _______________________________________________ PLUG mailing list PLUG@pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
