Error: netavark: create veth pair: Netlink error: Cannot allocate memory (os error 12)

The Memory I think was due to several processes on this shared server had backed up and tmp was almost full.

My containers are not in /srv but in /apps/opt/application/docker/volumes/b2b9ba16e60de58131d57d1fb229238d70b784fe7470e02d268f6d7db2859562-2025-03-24-142715

Did you have to modify the script in some way?

Sorry for the delay.. Basically I read the script and it looks like the very last command failed.. I ran that command manually and setup finished.. Sadly I do not remember what the last command was that I ran.. but it was in the logs.. I copy/pasted it and all was well.. It may have been sometimeout error as the system was pretty busy during the upgrade process
