Clear Systemd Journal Logs in Ubuntu 20.04

Systemd has its own logging system called the journal, and the log files are stored in /var/log/journal.

Check current disk usage of journal files

sudo journalctl --disk-usage

Rotate journal files

• Active journal files will be marked as archived, so that they are never written to in future.
