Issue with latest build of Karsten’s docker labwc container?

[scottwalsh]

Apologies if the title is an incorrect conclusion.

As using MagicMirrorOs that uses Karsten’s docker build.

Noticed my screen at a tty login prompt instead of displaying my configuration that has been running a couple of weeks.

After investigating a little, I can see the labwc container keeps restarting with the below error messages in the logs.

It looks like it did pull of the latest version of the container ~3 hours ago, and I see that is when a new version of the content was published.

• Is there an issue with th*e latest version of the labwc container?
• Or any suggestions on troubleshooting?

Some friendly trouble-shooting help
===================================

If a seat could not be created, this may be caused by lack of permission to the
seat, input and video groups. If you are using a systemd setup, try installing
polkit (sometimes called policykit-1). For other setups, search your OS/Distro's
documentation on how to use seatd, elogind or similar. This is likely to involve
manually adding users to groups.

If the above does not work, try running with `WLR_RENDERER=pixman labwc` in
order to use the software rendering fallback

fixed now, you can restart the pi (it will need some time to pull the new image before working) or

cd /opt/mm/run
docker compose pull
docker compose up -d

@scottwalsh

Thanks for the finding.

The labwc image is built weekly and after a first look in the logs (comparing to the week before) it seams seatd is not installed anymore.

Have to dig deeper …
