Not possible to install plugins after restore configuration

I am experiencing difficulties installing plugins after a restore of my configuration.


  • New image on SD card
  • Installing previously used plugins
    • Tuya
    • Onewire

System says it’s updating, but after restart no installed plugins …

Is there a way to troubleshoot this? Maybe manual installation of these plugins?



Hi Foenky,

hmm… Yes, perhaps try to do that manually. If you ssh into the rpi, try sudo apt-get install nymea-plugin-... If you hit an error message, please let us know.

You could also try to sudo apt-get dist-upgrade to see if any error happen.

Well I definitely got an error:

sudo apt-get install nymea-plugin-onewire

dpkg config problem?



Hmm… This really looks like you’ve unplugged the rpi in the middle of an “apt-get update” operation… According to the internet (here) you should be able to fix it with:

sudo dpkg --configure -a
sudo apt update
sudo apt upgrade

I will save my curent config and redeploy the image again.
A lot quicker, because the actions to fix it doesn’t work for me.
