Docker container does not start anymore, cron: unrecognized service about lychee-docker

[d7415]

Hi. Which architecture are you using? I can't replicate this on amd64.

[alexwild]

I have tested the installation now on three different systems.
My main server (still) runs on Debian buster (Linux nodename 4.19.0-21-amd64 #1 SMP Debian 4.19.249-2 (2022-06-30) x86_64 GNU/Linux)
On a second system, which runs on Debian bullseye (Linux nodename 5.10.0-14-amd64 #1 SMP Debian 5.10.113-1 (2022-04-29) x86_64 GNU/Linux) their the container seems to run fine.
Finally I tested a fresh Debian buster (Linux nodename 4.19.0-21-amd64 #1 SMP Debian 4.19.249-2 (2022-06-30) x86_64 GNU/Linux) installation in a vm, and this system has the same issues with the container.

That's very odd that the presence of cron in the container is apparently dependent on the host OS.

I'll see if I can think of anything - a cursory search didn't show up anything - but I'm not hugely hopeful.

One possible option would be to stop a failed crond from failing the container (e.g. appending || true to the start line). This isn't ideal though, and I'd rather understand why before adding workarounds.

It might not be the host OS, but the hosts kernel, as this used by the container. For debian buster it is still Linux 4.19 and for debian bullseye it is Linux 5.10.
I also noticed something even more strange when I tried to build the docker image locally, because this possible either. When I start directly a container and bypass the entrypoint and try to update the system this happens (this is also what happened when I tried to build the image):

But for the Linux 5.10 system it runs fine

Like I suspected, I could solve the issue for me by just upgrading my main server from debian buster to debian bullseye.

[d7415]

Those apt errors are even weirder... I'd like to know why, but for now I'm glad the upgrade solved it. At least we're still supporting stable and are only leaving oldstable behind for whatever reason.

Thanks for the update!
