I'm the original reporter of the issue. I was asked whether I could test
a pre-release of cloud-init for this bug and respond with results in
this launchpad issue (original report [on
Github](https://github.com/canonical/cloud-init/issues/5971)).
But beforehand:
> Since [...] the cloud-init team has no Hetzner access, there is currently no
> known way to reliably reproduce this
Did you intentionally decide against an account or is it just due to
budget? I talked to my colleagues at Hetzner Cloud. We'd like to offer
the cloud-init project credits for 20 Euro / month, so that you can test
and debug yourself on Hetzner Cloud. According to my colleague the
process is like this: You'd create an account first, tell us your
account number and we then assign the credits. I saw there is a contact
feature on launchpad. Feel free to contact me via that (I guess it gets
forwarded to my email address?), otherwise you could also create a
ticket at Hetzner and mention "Hetzner Cloud, Team Open Source
Integrations", it should then reach the correct department.
But now to my testing results.
The `ERROR` messages are now gone, but the exit code for some reason on
Ubuntu 24.04 is still `2`. Is there a way to find out what caused this
exit code?
## Ubuntu 22.04 (just for reference, here we had no problems with the exit code)
