It worked a few days ago (at least under my personal GitHub account), but is failing now:

Maybe this is something temporarily that will resolve on its own, or maybe we need to fix it, @vt-alt.

I tried re-running the job and it failed again exactly the same.

[vt-alt]

It seems that these issues (with old mkosi and diverging Ubuntu's debootstrap) become more and more complicated (to debug).

[solardiz]

@vt-alt Any chance you'd fix this now, as I am about to merge lots of changes and make a release? Thank you!

[vt-alt]

Are you hurrying? I thought it's waitable until weekend.

They started to prepare mainline kernels for an upcoming release, and debootstrap is missing it's script.

E: No such script: /usr/share/debootstrap/scripts/noble

I don't yet know how to properly install it. [Maybe some update channel could be added to the system (which is on jammy). We need to find this out.]

[solardiz]

I'm hurrying to release 0.9.8, which I intend to do today or tomorrow. It would be great to have CI fully working at release time, but not strictly necessary.

[vt-alt]

We need debootstrap (1.0.134) and it's not available via jammy-proposed repo. I think we can use Ubuntu's debootstrap git repo and install it into /usr/local/bin. Already tested it to work manually.

It could be cloned with --depth 1 into /debootstrap (so we don't need to set DEBOOTSTRAP_DIR) and then symlinked into /usr/local/bin (if it's first in PATH (untested).

Great. Are you going to send a PR implementing this? Thank you!

[vt-alt]

This is curiously quick.

[solardiz]

Thank you for fixing this so quickly, @vt-alt! I am releasing 0.9.8 now.

[vt-alt]

Btw, why don't you make github release with at least short description. I think they are useful for user visibility.
