I performed a series of updates after returning from holidays. I updated 26.1.8_5 --> 26.1.11_10 --> 26.7.1_1 --> 26.7.2_2. The apcupsd plugin no longer starts and on the dashboard it states "Error: empty output from apcaccess". I think it broke already with the update to 26.1.11_10, but I am not sure.
Is this a known issue? There is no error in the log, just a notice that apcupsd is starting.
If you have installed NUT on your system and you are monitoring the APC UPS using the apcupsd driver, you will encounter problems.
