Hi @jacqhesh Thanks a lot at this thread, too. :)
I don't think an agent updated to a higher version than the server is better. I just wanted to figure out if it's necessary to avoid this situation and if so ... how.
I understood I should avoid.
Based on my current knowledge I used the repository provided agent for the first client and so I thought if this could be updated without purpose (by simply running the well known apt update -> apt upgrade).
So I will have to get familiar with agent packaging to avoid unwanted agent updates (of course taking care about server updates as another task). Correct?
Thank you
