Podman cannot pull image

I had have docker, but it has conflicts with my Fedora 31 and I had to remove docker:

dnf remove docker-ce

rm -rf /var/lib/docker

because Podman is more suitable to work with. But hence after running

dnf install podman

I have docker and postman installed on my system. So, when using command:

podman pull fedora:latest

this log appears, which seems to be a some sort of conflict there

I tried to remove docker, but bash deletes it along with podman.

As @Giuseppe Scrivano wrote above, issue might be with files /etc/subuid and /etc/subgid As a source: https://www.redhat.com/sysadmin/rootless-podman: "This file is formatted as :<start_uid>:, where start_uid is the first"

So, I just added a line with "my-username":100000:65536 and it worked

  • replace "my_username" with yours

The error says requested 192:192 for /run/systemd/netif ie this image has files owned by UID 192 and you are running podman as rootless. Due to that, the image would not fit into rootless Podman's default UID mapping, which limits the number of UIDs and GIDs available.

Do cat /etc/subuid and check UIDs allocated for your user and probably could set additional IDs.

you are using rootless (running containers as non root) but it seems your user has not enough additional IDs available.

You need to make sure there are enough ids allocated for your user, please take a look at subuid(5) and subgid(5) to see how to configure it

After you set additional IDs for your user, you'll need to run podman system migrate to recreate the user namespace
