I’ve had an Ubuntu 22.04 setup going for around a year, and over that year I’ve had to increase the size of the partition holding my /var folder multiple times. I’m now up to 20GB and again running into problems, mainly installing new apps, because that partition is again nearly full. I’ve used commands sudo apt clean and sudo journalctl --vacuum-size=500 to temporarily clear up some space, but it doesn’t take long to fill back up, and gets less effective with time, til I have no choice but to expand the partition again.
Am I doing something wrong? Is it normal to need 20GB+ for var? Is there a way to safely reclaim space I don’t know about?
If I had to guess, I’d say it’s probably snaps. I’ve had the same issue and they’ve slowly been taking up more and more of my space, often with new gnome snaps being installed but the old ones not removed.
Try “snap list” to see what’s installed as snap
