Hi @eporart,

Please refrain from creating duplicate discussions. They may cause confusion with forum users and may also be removed by forum moderators if considered redundant. I would recommend renaming the current discussion to avoid such redundancy.

I researched the installation steps from the official podman documentation and several blog posts, and it seems that some inconsistencies are preventing the podman package from getting installed at this time. After several trial attempts, the following sequence of commands seemed to work. Please run the sequence as the student / or non-root user:

. /etc/os-release

echo "deb http://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/xUbuntu_${VERSION_ID}/ /" | sudo tee /etc/apt/sources.list.d/devel:kubic:libcontainers:stable.list

curl -L "https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/xUbuntu_${VERSION_ID}/Release.key" | sudo apt-key add -

sudo apt update

sudo apt upgrade -y

sudo apt install -y gnupg2

sudo apt install -y podman

sudo apt install -y podman --fix-missing

If the errors persist, re-run the following sequence:

sudo apt install -y gnupg2

sudo apt install -y podman

sudo apt install -y podman --fix-missing

sudo apt install -y gnupg2

sudo apt install -y podman --fix-missing

Regards,
-Chris

thanks Chris!! I applied re-run steps and works for me

student@student:~$ podman --version
podman version 3.4.2

Hello @chrispokorni ,

I have the same problem.

I run a ubuntu (22.04.5) on a VM with enabled nested virtualisation.

I have followed the steps you provide in your former answer to this question.

Everything went well until I reached the command

$ sudo apt install -y gnupg2
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package gnupg2 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
gpgv gpgsm gnupg-l10n gnupg dirmngr

So I tried
$ sudo apt install -y gpgsm & $ sudo apt install -y gnupg-l10n

Then when running
sudo apt install -y podman and sudo apt install -y podman --fix-missing

but both commands yield the same error message

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
podman : Depends: uidmap but it is not installable
Recommends: podman-gvproxy (= 4:4.6.2-0ubuntu22.04+obs81.12) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

I did succesfuly download podman-gvproxy
sudo wget https://github.com/containers/gvisor-tap-vsock.git

but then, when tryingto run again commands
sudo apt install -y podman and sudo apt install -y podman --fix-missing

The same error message was displayed.

Please kindly advise. Thanks

Hi @josepmaria,

There is a note in the Podman installation exercise that may clarify how to install the package on your Ubuntu release, which seems to be newer than the release tested for labs.

Hi @chrispokorni ,
