HI
I believe the patch Manager can deliver patches to the same supported platforms as the agents so you can go by this list from the CA Client Automation Compatibility Matrix
As for linux versions not listed for agents support we have a linux variant support statement and it can be found t this link
Compatible Linux Variants Support Statement
PLease advise if we can assist you further and if your questions are answered please mark the question as answered.
Thanks and Best Wishes for a good new year
Joe
