Intervention report 2017-01-12
- Description
Login was broken on all machines of the space and ps1auth was complaining a lot about other stuff. Took over someone that was trying to correct it but had to leave.

- Problem
- Seen some libraries problems on the ps1auth VM. Tried to update them. Then started the clusterfuck.
- Resolution
- Did a full update of arch on ps1auth. - Only some stuff got through - Had to disable GPG signing of packages for that using sed to modify pacman.conf, because nothing else was working - Did the update - Rebooted bob, resolved the initial problem of machines not logging, but I had to do that two times - Had to reconfigure network because interface name changed - As python was updated had to recreate the virtualenv of ps1auth - Had to update some packages (beautifoulsoup4, kombu add django-ldap something) because they failed with the new python - Rebooted the machine to be sure everything was ok - Got home.
- How to avoid the problem in the future
- Well I had to learn how things worked on the fly. We plan on updating the
infrastructure to more maintenable systems (arch was a big problem here as it was not updated for a long time).
- Have emergency clone VMs to restore quickly (if one has to leave before finishing upgrade/maintenance etc)?
