It is an Emonpi, and it was updated early this year, so the base system is now emonSD-30Oct18.
It is working normally again (apart from the missing Backup link), so the issue appears to have been the incorrect links in the emonhub.service file.
Thanks @julesb yes there has been a change to the emonhub service config but the update script should handle that update process correctly - at least it did when I last tested. Perhaps something tripped it up during the update. Is sounds like you have it sorted. If anyone else experiences this please let me know.
The backup module is installed at /home/pi/backup and the emoncms UI part of it /home/pi/backup/backup-module should be symlinked to /var/www/emoncms/Modules/backup. To update the module manually you could try:
cd /home/pi/backup
git pull
ln -sf /home/pi/backup/backup-module /var/www/emoncms/Modules/backup
I will double check the update process, this should all be handled automatically, at least it did last time I tested.
Do you by any chance have a copy of your emonpiupdate.log for the last update @julesb? Its available from the administration page.
I did an install 3 times. The first one is the one that stopped Emonhub from running, and it had similar issues with avrdude. The first log was overwritten then I attempted the update again. This got stuck on ATMega328 upating and was truncated when I shutdown the device, although I had copied the log lines before rebooting. That one is shown below.

> service-runner: no process foundHello @julesb the update shows local changes to both the emonpi repo:
modified: lcd/emonPiLCD.cfg
and the emonhub repo:
modified: conf/default/emonhub
modified: service/emonhub.service
Did you make these changes? If you didnt make the changes, or dont need to keep them you can clear them manually like this:
cd /home/pi/emonpi
git checkout .
cd /home/pi/emonhub
git checkout .
If you then run the update again and repost the log it would be interesting to see if that fixes it.
I will have a look later in the week when I have more time. The changes to the emonhub repo are probably mine, but I did not make any changes to the emonPiLCD.cfg file.

Hi
Running:
cd /home/pi/backup git pull ln -sf /home/pi/backup/backup-module /var/www/emoncms/Modules/backup
Recovered backup menu but is showing this:
Error: missing backup config.cfg
Any suggestion how to recover this features as 9.9.5 version=
Thanks

Hi
Also detected if you reboot emoncms then ln has dissapeared and backup module not showed, and also since latest upgrade emoncms.log has dissapperared, if you create folder and log, works, but after a reboot is lost this configuration and manual regenerate is required
Thanks

Yes, I just actually tried backup and same issue:
**Error:** missing backup config.cfg
Has happened to me now @TrystanLea ā¦
Donāt suppose this is an easy fix for this - havenāt backed up for a while now? Not super keen to do a full update if I donāt have to given issues so far post-update.
Hi Sam, itās not clear (to me anyway) what issue(s) you have, are you now saying the only issue you have is " Error: missing backup config.cfg"?
Your previous post
Quotes 2 passages about emonhub failing, is emonhub now ok?
And your post prior to that
whilst it quotes **Error:** missing backup config.cfg it follows a post by klx (replying to you) saying that the fix to the symlinks isnāt sticking and after a reboot the backup link disappears again. Do you also see this problem?
If it is just a simple case of the config.cfg file not found I think @TrystanLea would probably suggest you just re-run the update, the config.cfg file is created if missing by this part of the update scripts
if you are not comfortable with that approach you can manually create the file using default.config.cfg as a starting point and edit the paths accordingly using the code above as a guide. That is how itās done when manually installing the backup-module (GitHub - emoncms/backup: emoncms backup module). I donāt have any experience with the backup module so I can only offer limited help, but if you arenāt able to create the config.cfg file yourself Iām sure we can work it out or someone else might offer up a copy of theirs?
Iām pretty sure $usrdir is /home/pi on all emonSD images thus far so most if not all the paths and settings can be read from the update code above.
If you do have other issues can you please give us more details?
[edit] There is also the question of why this happened in the first place if only to predict or head off it happening when you next update. Can you attach a copy of your full update log? The likelihood is there maybe a reason it didnāt originally complete successfully and if so, we should try and fix the cause rather than just the results to avoid further problems.

Sorry Paul, I probably should have done a summary and not been so quote post lazy!
- RE: emonhub issues, I got that working again from your advice
- I lost the original 2 x updates logs i ran when all the issues started moving to new updates
- Realised I had no āBackupā option in the dropdown cog
- Ran @TrystanLeaās suggestion (cd /home/pi/backup git pull ln -sf /home/pi/backup/backup-module /var/www/emoncms/Modules/backup) restored the menu item
- But when I click āBackupā I get that config error - Error: missing backup config.cfg
I just tried re-running the Emoncms update from Admin page, log:

Aborting
and the emonpi repo is the one with all the updater code so itās the foundation for a successful update (or not!).
Do you recall what changes you made to emonpi/lcd/emonPiLCD.cfg ? Chances are it was the backlight timeout, this error has popped up a few times since this commit
anyone that manually edited that value prior to this commit will have had all updates to the emonpi repo blocked since that commit was merged.
to fix you can run
git -C /home/pi/emonpi checkout -f -B master
(or any of many alternative commands) to reset the repo changes. Thatās assuming you are ok with losing any manual changes youāve made, obviously the timeout will be 300 after the update but you can change it again if you so choose.
Then run the updater again. Then retry the backup link
