  • I have a SSD and not much space for temporary files with more then 2GB. My elementary OS partition is only 18GB and i have a lot software installed. How to prevent temporary files from growing above 2GB or less? And what is "Rotated logs" logging, only the Firewall? ![BleachBit - System Rotated logs 12GB](i.stack.imgur.com/yGVmw.jpg)

This is likely caused by a firewall misconfiguration (which is what ufw is), which can be modified to run in low-logging mode with this simple command:

sudo ufw logging low

Then you will probably want to clear up some space.

1. Rotate your Logs

sudo /etc/cron.daily/logrotate

2. Remove old Logs

sudo rm -Rf /var/log/*.1 /var/log/*.gz
