Pending updates status of one of the nodes in my testlab isn't updating anymore in the panel. I've seen it before when apt ran into locked files and could not be executed but that's not the case now. Apt update and apt upgrade run manually just fine. I've already been searching in ispc db's if a cron might be hanging but can't find any. Any pointers to where else to look?
Run server.sh on the affected slave node to see why it fails, you might als want to enable debug mode on master for that slave. The most common reason is a MySQL connection error / wrong password between the slave and master.
Couldn't find any issues like that, though pending updates wasn't the only thing. Also logs didn't update in the panel. Looks like a reboot solved it, though I'll have to wait until next pending updates to know for sure. Logs update again.
