Linux - could not get iptables version: exit status 111

MadByteDE · November 26, 2022, 9:44pm

Hey everyone,

I use Tailscale from my home directory with a systemd --user service on a recent SteamOS 3.4 update preview (Arch, Steam Deck).

After the new OS update, it seems like my tailscale installation stopped working with the error above.
Here is a more detailed explanation with logs.

Maybe any of you got an idea what the issue might me Maybe some changed permissions or something similar?

Thanks in advance!

I’ve got the same problem, did you solve it somehow?

My current solution:

# Instructions

Make sure you have a password set for `deck`, because the install script will need sudo to suid root the `tailscaled` binary.

* Create folder `tailscale` in home directory of `deck` user
  `mkdir -p ~/tailscale`
* Make install script executable
  `chmod +x ~/tailscale/tailscale-install-user.sh`
* Run install script
  `./tailscale/tailscale-install-user.sh`

tailscale-install-user.sh

#!/usr/bin/env bash

set -euo pipefail

dir="$(mktemp -d)"
pushd .
cd "${dir}"

tarball="$(curl 'https://pkgs.tailscale.com/stable/?mode=json' | jq -r .Tarballs.amd64)"
version="$(echo ${tarball} | cut -d_ -f2)"
