Ok. I put with echo into sources list all repos back and it showed some
possible upgrade again. I started upgrade in hope to upgrade the mate desktop
so that it fully apply. And after a night of upgrade it stuck and I had to
press the switch button. Now when I try to boot the comp trisquel 9 demands
login and password that I never had. This I see in grub:
Trisquel GNU/Linux 9.0 [the name of PC] tty1
[the name of PC] login:
and it waits. I never had any login anywhere. I don't know any login. What do
I do?
