My Ubuntu 20.04 suddenly stopped coming up. I enter a password, things crank for a bit, and then I am asked for a password again. This can go on and on.
I am able to bring up 16.04, and using it, I have done a bit of sleuthing, I have determined the following: The attempt to being up 20.04 creates the following files in /var/log
auth.log
boot.log
gpu-manager.log
kern.log
mail.err
mail.lor
syslog
wtmp.log
Xorg.0.log
Using grep I have checked for the word "error" (case-insensitive) and it is found only in kern.log, mail.err, and syslog. Attached are these files:
mail.err
kern.err (error lines from kern.log)
syslog.err (error lines from syslog - entire syslog available if requested)
I would greatly appreciate any enlightenment about what is going on and how to fix it.
