Installing on Ubuntu 20.04 from binaries alone

[CharlesJQuarra]

Since the podman version available for ubuntu 20.04 is ancient (3.4), and I can't be bothered to install 10Gb+ for a go toolchain and all dependencies, I downloaded the binaries available here, as well as gvproxy:

$ gvproxy --version
gvproxy version 012bc90

$ runc --version
runc version 1.1.11
commit: v1.1.11-0-g4bccb38c
spec: 1.0.2-dev
go: go1.20.12
libseccomp: 2.5.4

$ conmon --version
conmon version 2.1.10
commit: 09bcded8e9c49cf1ff1fda403feac5a08f22535f-dirty

At this point, if I run

 $ podman info
    OS: linux/amd64
    provider: qemu
    version: 4.9.0
    
    Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM
    Error: unable to connect to Podman socket: failed to connect: dial tcp 127.0.0.1:41191: connect: connection refused

So, it seems something is missing, however I'm able to use a Qemu VM with podman machine init and podman machine start, this is the result afterwards of running podman info:

I was under the impression that you didn't need a Qemu machine under linux, but it seems there should be something missing in my installation

The podman installation guide gives no details on how to install from the provided binaries, so I just added them all to $PATH (which seems to have brought me up to 80% accomplishment)

[afbjorklund]

Only the podman-remote client binaries are provided by the release, to get the podman server you need to build from source.

Newer versions of Ubuntu have newer versions of Podman, but it is not backported: https://packages.ubuntu.com/podman

• How to install podman 4.4 on Ubuntu 22.04? #17362

• Version 4.x not updating with apt update Ubuntu 20.04 #14302

[lstolcman]

There is kubic repo: https://podman.io/docs/installation#ubuntu

But due to updated version of go, which is not existing on older ubuntus, build is not working:
https://build.opensuse.org/package/show/devel:kubic:libcontainers:unstable/podman

I fixed the build script couple days ago, it succeed but it did not get merged yet:
https://gitlab.com/rhcontainerbot/rpms-openqa/podman/-/merge_requests/5

I saw the kubic unstable is managed by @lsm5 but he posted a comment somewhere in the discussion that he dont have time to manage it.

@rhatdan @vrothberg @giuseppe - could you advise how to push it forward?

I'm willing to work on fixing ubuntu build, as well as the ubuntu documentation (after build script got merged)

[afbjorklund]

I think the plan was to remove the "kubic" references, but maybe you could start a new OBS project for Ubuntu LTS?

• Remove Kubic references for Debian and Ubuntu podman.io#240

[lsm5]

20.04 is really old and was never built on kubic-unstable. Maybe you wanna try forking the kubic repo and enabling 20.04 over there. If things work, we can look further.

FYI I was able to install successfully using this repo: https://github.com/mgoltzsche/podman-static

The only absolutely minor inconvenience is that I had already some work and images on the qemu VM, but I will remove that now and rebuild

thanks for the replies
