I did upgrade via the Admin console of EmonPi. After the update the “Input Process” stopped working.
The data that is sent to emon is comming through (Via node red and the Emon Node) but it is no longer been processed.
See screen shots

I can also not add an process as it seems missing.
Looking at the console on the admin page if I attempt to upgrade emonpi again I get the following

Starting emonPi Update >

emonSD version: emonSD-26Oct17

ERROR: emonSD base image old or undefined…update will not continue
See latest verson: emonSD pre built SD card Download & Change Log · openenergymonitor/emonpi Wiki · GitHub
Stopping update

Is there a way to fix this?

It seems support for the emonSD-26Oct17 was (accidentally?) dropped in a recent commit

I’ve submitted PR’s for this version to be reintroduced but even once those fixes are in place, you won’t be able to pull them in as support for your image has been temporally removed so the update won’t run to pull in the fixes.

A work around is to edit the version file to a supported version so the update will run and then change it back so as not to cause any further confusion caused by reporting the wrong base image.

If you ssh in and run the following from the command line

sudo mv /boot/emonSD-26Oct17 /boot/emonSD-13Jun18

you should then be able to update as usual and then after ALL the updates are done (ie update now and then again when the fix to the versions is merged by @glyn.hudson )

sudo mv /boot/emonSD-13Jun18 /boot/emonSD-26Oct17  

you could then try running the update again just to be sure all is hunky-dory.

As for your original “processing” issue, I’m afraid I haven’t a clue, but it’s worth asking, have you tried clearing the browser cache? (ctrl-f5)

Good job it is enabled… GRD (for the youngsters amongst you, Grinning Running Ducking)…

I realise the code to force a browser refresh of cached content on the input and feed list pages was not included. I have added this in now (including updating stable) Force browser cache reload by TrystanLea · Pull Request #1077 · emoncms/emoncms · GitHub to help avoid the need for a manual clearing of browser cache.

Thanks also for your fix @pb66. I have merged both in. For those who have pressed update in the intervening time and who see:

ERROR: emonSD base image old or undefined…update will not continue

a manual fix is required unfortunately as @pb66 explained. Perhaps the preferable fix is to update the emonpi repository rather than changing the base image file?

cd emonpi
git pull

Or those of us on the other side of the pond… :grin: :wink:


Thanks so much for the fix @pb66. I’m very sorry for causing this hassle, totally my fault. I’ve created a new thread to make clear the steps required to fix this issue for any users effected:

A fix for the Process List Unavailable issue submitted by @TrystanLea has now been merged into the Emoccms core stable branch and released under V9.9.2.

Re-running emonPi update or a manual git pull on the Emoncms core should fix the issue. Alternatively manually clearing the browser cache should fix the issue by forcing the browser to load the updated resources.

Apologies for the hassle, thanks for the support.

Is this comment directed towards our recent efforts to increase security by disabling SSH? If you have any comments to make please voice them in the thread

For the record enabling SSH would only require a 5-second press-and-hold of the push button the emonPi. In my opinion, 5 seconds of a users time is a small inconvenience for the significantly increased security.

This sorted my problem , Ill remember in future to check this first. Thanks !

thanks for the support. should also remember the ctrl-f5 browser refresh.
its working after updating to 9.9.2

Oh @glyn.hudson, did you not get the GRD bit??? :smiley:

Once enabled, does it stay enabled?
