If Im reading this figures correctly ('df -h' is much nicer) your / has
somewhere near 2,8 GiB and is full. Considering you have separate /usr
(which has only some 1,2 GiB) and /var this sounds fishy.

Good.

2,9 GiB for / with separate /usr and /var should be plenty. I'd suggest
looking into what is using all that space.

These "should" reside in /usr, so in theory wouldn't help much with your
immediate problem.

See if unused Linux images are installed
dpkg -l linux-*
Removing one could already provide some breathing space, but I would
keep at least two around (the one in use, obviously, and next older
one).
You might want to check the output of
du / -hx --max-depth=1
To see where the 2,9 GiB are, but my bets are on /opt ;)
Kind regards,
