Can I get a newer podman on Silverblue 29?

Project Discussion

The podman version included in the base image is kind of old at this point (0.8.4, latest is 0.9.3.1). Right now I have a weird issue with --net=host and the Debian Docker image (which is weird because this never happened before…), but I need to see if it still reproduces on the latest podman (and even then, I’d want to be able to install it).

The COPR is probably not going to work because you can’t override base packages. The best idea I have right now is maybe rpm-ostree usroverlay + extract the podman rpm contents over the existing install. That doesn’t quite feel right though, so I’m trying to see if I can get a newer version in a “proper” way.

FWIW as a side note, the podman issue I’ve found is:

 ryan@fedora  ~  sudo podman run --rm --net=host debian:jessie useradd user
useradd: failure while writing changes to /etc/passwd
 ✘ ryan@fedora  ~ 

It works without --net=host or with pretty much any other image.

Sure you can! The command is just a little different (rpm-ostree override replace):

It looks like your issue is fixed in that newer version:

$ rpm -q podman
podman-0.9.3.1-1.git1cd906d.fc29.x86_64

$ sudo podman run --rm --net=host debian:jessie useradd user
