Thanks, that helped. I could go back to the previous setup.
mmpm still doesn’t work, though. I think I installed it wrong but need to dig deeper.
If I just ssh on the PI I can use mmpm but If I go into the mm container with docker exec -it mm bash it cannot find the mmpm command. Now I need to figure out how to remove my mpmm installation.

/home/node/.npm/_logs/2021-10-29T20_22_53_399Z-debug.log

the file is in the container, after executing docker exec -it mm bash you are in the container and then you should be able to see this file.

But the whole thing is strange.

You could reset the setup by

• stop the container: navigate to ~/magicmirror/run and run docker-compose down
• test there is no container running with docker ps
• navigate to home directory executing cd
• rename magicmirror folder with mv magicmirror magicmirror-old
• reboot your pi

While starting the now missing magicmirror folder will be recreated from scratch.

docker ps shows

CONTAINER ID   IMAGE                          COMMAND                  CREATED      STATUS          PORTS     NAMES
04fcaa798d2e   karsten13/magicmirror:latest   "/usr/bin/tini -- ./…"   3 days ago   Up 28 minutes             mm

and the first error in the log is

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! magicmirror@2.17.1 start: `DISPLAY="${DISPLAY:=:0}" ./node_modules/.bin                                                                          /electron js/electron.js`

However, /home/node/.npm/_logs/2021-10-29T20_22_53_399Z-debug.log does not exist.

What else is changed after reboot with the other container?

nothing

You can look into these yaml files, it`s all text.

You can see which containers are running with docker ps and may something is in the logs docker logs mm.

It takes some time pulling new images (this is done after a reboot).

I did the cp ~/magicmirror/run/rpi_mmpm.yml ~/magicmirror/run/docker-compose.yml and reboot but got a black screen for the MagicMirror. So I replaced docker-compose.yml by the original file and rebooted again but the screen is still black.
I don’t know much about docker containers. I tried docker exec -it mm bash and it opened as usual.
What else is changed after reboot with the other container?

Does anything of this makes sense to you?

not really … never tested this setup.

Would try to run with 2 containers, setup here.

You have already all the files in ~/magicmirror/run/ folder, just save the content of docker-compose.yml (only if you changed something) and then cp ~/magicmirror/run/rpi_mmpm.yml ~/magicmirror/run/docker-compose.yml and restart the container.

MagicMirrorPackageManager

The debug console on the mmpm shows an error that it couldn’t find a favicon and several source map Errors (as Warnings) like :

Source-Map-Fehler: Error: request failed with status 404

Its also the

• assets/monaco/vs/loader.js
• assets/monaco/vs/editor/editor.main.js
• assets/monaco/vs/editor/editor.main.nls.js
• assets/monaco/vs/base/worker/workerMain.js#editorWorkerService
• assets/monaco/vs/base/worker/workerMain.js#json
• assets/monaco/vs/editor/editor.main.nls.js

with the same Warnings. Plus it complains about the zoom property.

Does anything of this makes sense to you?

Or can it be the installation procedure? I installed the Docker-based MagicMirrorOS. Do I need to install the mmpm also via the Docker route?

you should check for errors when loading the GUI in the browser, CTRL+SHIFT+I opens then console.
