[HTCondor-users] Condor removed after Ubuntu updates

[Nils Irland <nirland@xxxxxxxxxxxxxxxxx>]

Hello all,

 

I’m a condor neophyte and have been playing around with some test setups to get the hang of it. I’m running condor on Ubuntu 20.04.3 LTS and my simply environment consisted of a submit / central manager node and 3 execute nodes, all installed via the getcondor script method.

 

Today I ran updates on those machines to install the latest patches and condor disappeared from all of them. Looking at dpkg.log in /var/log I can see the notes of it getting uninstalled, but I have no idea why. Is this something else anyone else has run into? Obviously having this happen in production would be a bad thing™ so I’d like to know what exactly happened but I’m not sure where to start. If anyone else has had this happen or knows a good place to look for artifacts of the uninstall, that would be great. I used Ansible to run the updates, so I don’t have the full command output of apt as it was run, just a list of packages updated, which looks fairly benign:

Thanks very much, and if anyone has any ideas or would like more information, please let me know!
