Podman can't download .application file

[AlexChalk]

Image runs fine with docker on my machine, but breaks with podman.

Modifications to run-mtgo:

docker_client=podman
limit_cpus=0
opts="--userns=keep-id"

I can then run the image, but the mtgo setup fails with error "An error occurred trying to download 'http://mtgo.patch.daybreakgames.com/patch/mtg/live/client/MTGO.application'"

I was having the same issue, I fixed it by changing my opts to "--userns=keep-id:uid=$(id -u),gid=$(id -g)" as I noticed that --userns=keep-id was still not mapping my uid properly.

I'm not sure if it is needed, but I also ran ./run-mtgo --reset first.

[etchevef]

I had something similar where what made it work was to first delete my .local/share/mtgo host repository (in addition to the --reset). Work with just the --userns=keep-id though
