Description Jordan Russell 2013-02-28 06:57:56 UTC
Description of problem:
While the nut packages are being upgraded with yum, an alarming "Communications with UPS lost" message sometimes gets wall'ed to the console.

It appears this happens because nut-server.service is stopped while nut-monitor.service is still running.

To avoid these spurious errors during upgrades, I believe it should stop/start the services in a specific order:
1. Stop nut-monitor
2. Stop nut-server
3. Stop nut-driver
4. Start nut-server (pulls in nut-driver automatically)
5. Start nut-monitor

Version-Release number of selected component (if applicable):

Comment 1 Michal Hlavinka 2013-02-28 13:28:20 UTC
Unfortunately, this is not that easy. nut-monitor and nut-server does not have to be running on the same system. They are split to two packages and we can't affect in what order packages are updated by yum.

I'll try to come up with some solution.
