Okay, I think it was file corruption, no idea how. The server is running as a VM on a locally-managed cloud infrastructure, so all I can do is submit a support req to the admins which they'll look at and probably ignore. I can't get the hard disk error stats.
Fixed by extracting the exceptions.rb file from a downloaded deb file, checking the checksum of that matched the one for the installed package, copied it over, did the upgrade. Everything working okay. -- You received this message because you are subscribed to the Google Groups "GitLab" group.
