Are there any Fedora/Docker experts out there?

My #Samourai #Dojo will not build after upgrading to Fedora 41. It seems like #Fedora is prioritizing Podman and there may be issues with their #Docker implementation. I'd rather not build a new VM (Ubuntu) just for Dojo but it seems it will come to that as I strongly prefer to be able to use the distro Docker packages and not have to install RPMs directly from Docker.

Any insights are appreciated!

I'm a recent convert to Fedora after 20 years with Ubuntu (some weird hardware issue pushed me over the edge, I don't remember the details). I also ran into this issue with Docker, and weird podman incompatibilities.

Looks like I installed docker-ce at some point, and things seem to be working for me. Happy to help you debug issues if that doesn't help out.

Thanks for offering to help, much appreciated!

Fedora 41 does indeed work fine with Docker and Dojo 1.26.1. My issue was that I somehow had a very old version of containerd installed. I had apparently installed the containerd version from Fedora 35 (perhaps there was an issue with the Fedora 36 version). It seems if you install a package manually without using dnf then dnf won't update it, even across major version upgrades.

After I removed the outdated version of containerd and installed the one from the repository everything works correctly and Dojo is now up and running.

For anyone that stumbles on this while trying to resolve an issue I ran this command:

dnf list --installed

dnf tells you the method by which a package on your system was installed. In the case of the problimatic containerd package it was installed via command line (I assume I manually installed an RPM package).
