That’s fine. I’m use to being unrepresented in the arj, lha, and uc2 crew

Btrfs and df don’t get along. There are all sorts of internals to btrfs that non btrfs utils ignore. You should run

sudo btrfs filesystem df /
sudo btrfs device usage /

It will give you a better picture of what is going on.

Balancing my help as someone above pointed out, or you may need to boot to a live media of some kind and rebuild the free space cache. Especially with btrfs I encourage people to join their mailing list for help. The devs are awesome and can help you get sorted out.

Btrfs uses subvolumes instead of traditional partitioning. It takes some getting use to but it is totally normal for btrfs.

Duh… Fedora not Ubuntu/Debian/Et al.

sudo dnf clean

It’s been a while since I have run a redhat derivative… I think that was either the last iteration of mandrake or the first iteration of mandriva.

And the journal isn’t garbage persay, it’s a bunch of logs and whatnot that can be useful in certain diagnostics… Especially with op running all those snap packages. But in this case, clearing it is probably a better option then not clearing it

Fedora is systems, right? The easiest way to gain some (temporary) space is to clean out the journal and whatever logs you don’t need. It can grow quite big.

sudo journalctl --vacuum-size=100M

Will shrink it to something manageable. This will buy you some time to clean up until the journal grows again.

Also, clearing the apt cache will probably help free up some root partition space

sudo apt clean

Your root partition where packages are stored and all the logs and transactional databases might be full even if your home directory has tons of free space.

Or - hear me out - or it is a bit of cotton on the end of an Ethernet cable.
