Had a similar thing at work not long ago.

A newly deployed version of a component in our system was only partially working, and the failures seemed to be random. It’s a distributed system, so the error could be in many places. After reading the logs for a while I realized that only some messages were coming through (via a message queue) to this component, which made no sense. The old version (on a different server) had been stopped, I had verified it myself days earlier.

Turns out that the server with the old version had been rebooted in the meantime, therefore the old component had started running again, and was listening to the same message queue! So it was fairly random which one actually received each message in the queue 😂

Problem solved by stopping the old container again and removing it completely so it wouldn’t start again at the next boot.

I’m a Norwegian Linux enthusiast and have never heard anything about the government using Ubuntu or Linux. Seems unlikely, from what I know. I know that within healthcare Windows is still widely used, even on the server side…

On the other hand, a lot of software for official services is being developed as open source now, so that’s at least a good step in the right direction. Example: https://github.com/navikt

You can self-host Bitwarden, and sync your vault to your phone. Maybe not an option for everyone since it requires some technical skills, but very doable.
