My password in Ubuntu 22.04.2 LTS is being rejected for authentication of updates, app install/uninstall, unlock, ... However, it does work when I log on after a restart. Until a week or so ago it worked for everything. How do I fix this?
Here's the output requested by @muru:
tim@tim-Precision-T1700:~$ groups
tim adm cdrom sudo dip plugdev lpadmin lxd sambashare
tim@tim-Precision-T1700:~$ sudo -l
[sudo] password for tim:
Sorry, try again.
[sudo] password for tim:
I guess, obviously, one of the consequences of the issue(s) I'm having is that I am unable to perform "sudo" commands.
Another issue that has presented, somewhat unrelated, is that I have not been able, so far, to get to the GRUB menu. not seeing the BIOS screen to signal when to hold down the SHIFT key. I'll keep trying.
Seems like I'm hitting a brick wall. Getting close to going radical and reinstalling Ubuntu, maybe 23.04 or a totally different distro.
