Docker latest tag does not work on RPi 4

[Tooa]

Problem statement

Running docker pull synesthesiam/rhasspy-server:armhf on my RPi 4 causes the following error:

failed to register layer: error creating overlay mount to /var/lib/docker/overlay2/b245a33c684fdcade3ac4fe5683636f9a252d5a4559c83f75e5551a8f722c086/merged: too many levels of symbolic links

Details

• docker pull synesthesiam/rhasspy-server:armhf-2.3 works
• I guess we reached the limit of docker layers for Raspbian here
  • In contrast, HASS.io is modified to run more docker layers (reference)

[synesthesiam]

This is surprising, since I thought the 2.4 image used far fewer layers than 2.3. Did they lower the limit?

Seems like this issue is resolved with the latest docker update (Docker version 19.03.7, build 7141c19). I'm now able to pull the latest docker image of rhasspy. Thus, closing this issue.
