I have a problem with my ubuntu 20.04 My /vat/log/journal grows to 195G. When I execute the command $tail -f /var/log/syslog I see a log repeated and I think this is my problem.

Sep 20 19:45:11 fanapsoft vboxdrv.sh[6730]: Invalid password
Sep 20 19:45:11 fanapsoft vboxdrv.sh[6730]: The Secure Boot key you've entered is not 
valid. The password used must be
Sep 20 19:45:11 fanapsoft vboxdrv.sh[6730]: between 8 and 16 characters.
Sep 20 19:45:11 fanapsoft vboxdrv.sh[6730]: Enter a password for Secure Boot. It will 
be asked again after a reboot.
Sep 20 19:45:11 fanapsoft vboxdrv.sh[6730]: Enter the same password again to verify 
you have typed it correctly.

I don't have any idea why this problem occurred. I remember last time when I upgrade ubuntu It wants to set a password for the next reboot but it doesn't get the password after reboot. Know I can't clear the /var/log/journal and when I run the $ sudo rm -rf /var/log/journal/* nothing happened.

Does this answer your question? [What is the use of systemd-journal-flush.service?](https://askubuntu.com/questions/1094389/what-is-the-use-of-systemd-journal-flush-service)

/etc/systemd/journald.conf has a setting to limit the size of /var/log/journal/*

SystemMaxUse={n}M

where {n} is the max size.

$ sudo rm -rf /var/log/journal/* nothing happened.

That is correct. rm only reports if it errors out.

You do need to restart your deamon though for it to take effect (or reboot) with sudo systemctl restart systemd-journald.service

So what is the correct form? _SystemMaxUse={1000}M_? or _SystemMaxUse=1000M_. That's when an good example is superior to any technical explanations.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
