I rebooted the tower-pc, via GRUB, into recovery-mode. Then I dropped to
the root shell prompt. And I remounted the filesystem with write
permissions.
I copied /etc/sudoers and /etc/sudoers.d/README to my Desktop directory.
Then I exited, followed by rebooting the PC.

After rebooting, both those copied files were locked; I couldn't read
them! Perhaps my machines had contracted a virus? So I opened Ubuntu
Software, attempting to install ClamTk. A window said "Authentication
Required", "Administrator" and asked for the Password. But, on entering
that, I got the error "Sorry, that didn't work. Please try again."!

/var/log/syslog is locked, so I can't read it!

That term is beyond my understanding!

None that I can think of!
