So, your computer has 3911M of apps in /usr/share.
My /usr/share has a somewhat less, but /usr/share is also non-trivial:
2023-03-02 14:27:31 root@laalaa ~
# du -m -d 2 /usr | sort -rn | head
5113 /usr
3158 /usr/lib
1578 /usr/share
970 /usr/lib/x86_64-linux-gnu
664 /usr/lib/modules
334 /usr/share/locale
286 /usr/lib/libreoffice
252 /usr/lib/go-1.15
215 /usr/lib/firefox-esr
206 /usr/share/doc
Looking at my /var:
2023-03-02 14:29:33 root@laalaa ~
# du -m -d 2 /var | sort -rn | head
1317 /var
974 /var/log
945 /var/log/journal
194 /var/lib
123 /var/lib/apt
86 /var/cache
68 /var/cache/apt
61 /var/spool
60 /var/spool/cups
60 /var/lib/dpkg
/var/log/journal is getting big. Following Felix' and Jeffrey's
suggestions, and RTFM journald.conf(5) and journalctl(1), I can imagine:
2023-03-02 14:40:48 root@laalaa ~
# cat /etc/systemd/journald.conf.d/local.conf
[Journal]
SystemMaxFileSize=5M
SystemMaxUse=50M
RuntimeMaxFileSize=5M
RuntimeMaxUse=50M
How do I verify the syntax?
How do I make the settings live (other than rebooting, which might hang
if there is a syntax error)?
