sorry for the late reply! my bad! I got the first set of errors fixed with the sudo command.
The second set of errors was as you said. my emonPi went into the read-only mode part way thru the emonPi update. I got two of those types of errors in a row (odd coincidence?).
I looked at the service-runner and all looked like a correct copy of the service runner on GitHub. But I do have a recent problem with redis.
I still haven’t figured out why I cannot get the emopi Update to run via the webpage. Too many odd issues! No worries, I’ll figure it out someday!
