[CollEc] CollEc app not starting

[Thomas Krichel]

  The CollEc trouble keeps me up at night!

  Apparently, it is possible to downgrade packages.

root at helos ~ # aptitude search docker | grep ^i
i  docker-ce - Docker: the open-source application container engine
i  docker-ce-cli - Docker CLI: the open-source application container engine
i A docker-ce-rootless-extras - Rootless support for Docker.
i  docker-compose-plugin - Docker Compose (V2) plugin for the Docker CLI.

  For the compose-plugin, this does not seem to work

Package docker-compose-plugin is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

  But maybe this is not required. Over to you Christian.
