Ubuntu installs fail with DEBIAN_FRONTEND=noninteractive: command not found

[quadespresso]

launchpad version: 1.4.0-rc.1

I've been trying to stand up a single-node cluster running on Ubuntu 20.04 (also seen on 18.04) and have repeatedly run into this:

[2022-05-13 17:48:17] DEBU [ssh] 3.98.139.172:22: executing `sudo -s -- DEBIAN_FRONTEND=noninteractive apt-get install -y -q curl apt-utils socat iputils-ping`
[2022-05-13 17:48:17] DEBU [ssh] 3.98.139.172:22: /bin/bash: DEBIAN_FRONTEND=noninteractive: command not found

If I switch back to an older version, the issue is no longer present.

I should have noticed this yesterday when I posted my session in this comment, as it's there plain as day: ssh unable to authenticate with Ubuntu 22.04 #366

At the time, I was expecting the actual MCR install to fail, due to the lack of jammy packages in the repo. So I tuned out the DEBIAN_FRONTEND=noninteractive: command not found as I was happy to see that launchpad was able to login via ssh using RSA.

Maybe they changed "sudo". This can be probably fixed by wrapping it inside bash -c.

sudo -s -- bash -c "DEBIAN_FRONTEND=noninteractive apt-get install -y -q curl apt-utils socat iputils-ping"

Yeah same happens in a vm.

ubuntu@foo:~$ sudo -s -- FOO=BAR env
/bin/bash: FOO=BAR: command not found
ubuntu@foo:~$ sudo -s FOO=BAR -- env
SHELL=/bin/bash
...
...

k0sproject/rig#60 this should fix it, it moves the variables before the --.
