Hi @craig.jeffrey,

It looks like your /tmp/ directory is mounted as read-only, which will make applications misbehave. Remounting the /tmp/ partition might help temporarily.

Regardless, it is likely worthwhile looking into why the /tmp/ mount ended up as read-only in the first place, as a read-only /tmp/ could be a sign of hardware failure.
