I used the instructions to found here to remove moby-engine and install docker-ce. But now zincati is giving a conflict when trying to update.

Is there still some remaining package that needs to be removed/cleaned up?
Hey @drogo - can you open an issue against the tracker for this?
I think the problem is that a new docker-cli package was added in F41+ and we should probably update our docs to also override remove any new packages as a result of that change.
Hi @dustymabe , Issue 1845 opened. I think I got everything in there that’s needed.
@hricky , I did what you suggested, and it successfully upgraded to 41.20241109.3.0, but commands to install docker-ce now fail with a similar dependency error;

I was trying to get docker-compose back, and it looks like that’s available simply via rpm-ostree install. So I can layer it instead.
The main reason when we introduced the Docker CE installation docs page a few months ago was that the Docker packages in the Fedora repositories were outdated compared to those in the upstream repositories. Recently, the Docker packages in the Fedora repositories were restructured and these days they are regularly maintained and synchronized with the upstream repositories. For more info, see Installing Docker and Docker-Compose :: Fedora Docs.
So, currently, I think replacing the Fedora-provided versions with those from the upstream Docker sources is more of a personal preference. In any case, as already suggested, I think we need to update our docs.
If you want to install Docker from the upstream sources on Fedora CoreOS 41, try the following command.
I switched to docker-ce because i kept running into strange issues with ulimits and the moby bucktracker had old issues which seemed like what was hitting me but stalled out and since it only happened after a few days with no clear reason i didn’t try further since the unreproducibility is what stalled the old issue in the first place.
Anyway i now want to update to 41while keeping docker-ce but can’t figure out how.

No. i didn’t want to risk switching docker engines back and forth for fear of sublte config incompatibilities or whatever might happen. maybe that fear is unfounded?
To be on the safe side, you can pin your current deployment. Then upgrade according to the instructions and test if everything works. If something goes wrong, you can always rollback to FCOS 40, but this version is EOL and no longer supported.
