Updates taking that much space is a bit surprising. I used to run linux mint on a 20 gb partition and usually had 3-4 gb space free. Does Linux mint comes pre-installed with flatpaks (you check with flatpak list
)?
But 20 gb is on the very low side, you will run into issues on updates. You probably need to extend the linux partition by at least 10 gb.
For the printer issue, check the status of the cups service (sudo systemctl status cups
).
Nice to see Incus doing well after canonical’s forced overtaking of the original project lxd.
