3.4. is ancient. We only supported the latest upstream release so please test with podman 5.2.
Second, please do not use screenshots of terminal text. Copy and paste the output please.

@Luap99
sudo apt-get update
sudo apt-get install -y podman:
For ubuntu by default 3.44 is installed using above commands, can you help me with how to install 5.2 for ubuntu 22.04?

[rhatdan]

You need to ask Ubuntu to update there version of Podman or switch to a distribution which is more up to date.

[Luap99]

see #17362, there are some third party repos listed that might work.

Hi @Luap99 : I am facing the same issue with podman version 5.2:

APIVersion: 5.2.0
Built: 1724222036
BuiltTime: Wed Aug 21 06:33:56 2024
GitCommit: ""
GoVersion: go1.23.0
Os: linux

Version: 5.2.0

"-volumes-from" -doesnt work; Can you please let me know if something is missing; The folders in image doesnt get mounted onto the container. The same works for docker.

podman create -v /test-repos --name testrepo localhost/testimage /bin/true

podman run -it --network slirp4netns --volumes-from testrepo docker.io/library/ubuntu:22.04 /bin/bash
root@dd3c4809b5ba:/# cd /test-repos/
root@dd3c4809b5ba:/test-repos# ls
root@dd3c4809b5ba:/test-repos#

podman run -it --network slirp4netns localhost/testimage:latest /bin/bash
root@90bb93fd90d1:/test-repos# ls
runtimeconfigs systems testcases testmatrices

[Luap99]

This works:

$ podman run --name c1 -v /test quay.io/libpod/testimage:20240123 touch /test/abc
$ podman run --volumes-from c1 quay.io/libpod/testimage:20240123 ls /test
abc

AFAICT copy up of volume content only happens on start time by default, you would need to set the prepare_volume_on_create option in containers.conf to achieve this behavior.
see #10262

Okay, thanks, this works!
