I think you maybe mixed up @Fra and me in this answer? my output from df -h is like this

Oops, sorry @Linevmo, more like I combined replies from both of you!

You have a few tmpfs devices that are dangerously low on disk space — is it possible that you forgot to reset TMPDIR in your env? You will need to export that anytime you start a new shell.
