Error after updating LAMP-App to 3.4.2

[RoboMod]

After updating a LAMP-App from 3.4.0 to 3.4.2 I got following error:

Docker Error: (HTTP code 500) server error - error creating overlay mount to /var/lib/docker/overlay2/dc16f22fedeaa91656319a27dff3b1878b7de4796f56881cc983f951c69435a4-init/merged: too many levels of symbolic links

Repeating the update task did not solve the problem.
Can you help me?

I only know this error from when Docker images got corrupted on disk, in which case purging that image from the system usually helps as docker will redownload those.

There is a larger thread about this at https://forum.cloudron.io/topic/10676/update-to-7-6-1-failing

The update to 3.4.1 worked? Or is 3.4.2 a typo?

Ah, sorry. That was my mistake. The update worked now (maybe after upgrade Cloudron to 8.0.3). Now the app is running version 4.0.0-1.
