If you run that grep command directly on the hosts what is the output?

[mattsoldo]

The grep command produces no output:

$ grep -q  "Raspberry Pi" /proc/cpuinfo
$ grep "Raspberry Pi" /proc/cpuinfo
$

Very interesting, that should gracefully error... Maybe comment out this code so it works, or try to debug it. I haven't had any other reports of this issue happening so I'm curious what's causing it. If you find it out please feel free to open a PR with a fix. Thanks!

Going to close this issue, please reopen if you're still stuck.

I had the exact same issue on an Ubuntu 22.04 LTS VM.

  msg: No package matching 'linux-modules-extra-raspi' is available

ssh-ing in and running the grep returns nothing.

[onedr0p]

Seems like something might have changed with 22.04, as No package matching 'linux-modules-extra-raspi' is available

Maybe it was changed to this package?

[onedr0p]

I have fixed this issue, meaning the code doesn't exist anymore for this check or installing linux-modules-extra-raspi. If anyone has an idea if this is still needed on 22.04, please open a PR 🙏🏼

[onedr0p]

Ok, after some confirmation I believe this is really fixed. d10800e

Closing issue, this should be fixed now and forever.
