[Bug 2024200] [NEW] [debootstrap] /usr/share/debootstrap/scripts/focal missing

[Eric Mergelsberg]

Public bug reported:

Recently we noticed failing unattended Ubuntu 20.04 LTS (Focal)
installations, because it stops with the following error message:

debootstrap: E: NOSCRIPT
debootstrap: EA: /usr/share/debootstrap/scripts/focal
debootstrap: EF: No such script: %s

It has been turned out that new packages of debootstrap has been shipped
that drops the symlink for ubuntu focal:

NEW PACKAGE VERSION:
<!----
-rw-r--r-- 1 root root 38752 Jun  8 02:09 debootstrap_1.0.118ubuntu1.10_all.deb
-rw-r--r-- 1 root root 26756 Jun  8 02:09 debootstrap-udeb_1.0.118ubuntu1.10_all.udeb
-rw-r--r-- 1 root root  2075 Jun  8 02:09 debootstrap_1.0.118ubuntu1.10.dsc
-rw-r--r-- 1 root root 79690 Jun  8 02:09 debootstrap_1.0.118ubuntu1.10.tar.gz

PREVIOUS PACKAGE VERSION:
<!----
-rw-r--r-- 1 root root 39166 Nov  7  2022 debootstrap_1.0.118ubuntu1.8_all.deb
-rw-r--r-- 1 root root  2034 Nov  7  2022 debootstrap_1.0.118ubuntu1.8.dsc
-rw-r--r-- 1 root root 80251 Nov  7  2022 debootstrap_1.0.118ubuntu1.8.tar.gz
-rw-r--r-- 1 root root 26984 Nov  7  2022 debootstrap-udeb_1.0.118ubuntu1.8_all.udeb
----->

After comparing this two releases, i noticed that the symlink to 'gutsy'
is missing now which is the reason for the failed unattended
installation:

lrwxrwxrwx 1 root root 5 Nov  3  2022 debootstrap_1.0.118ubuntu1.8/usr/share/debootstrap/scripts/focal -> gutsy

Checking out the upstream source code, it seems to be still there, but
for whatever reason the new package version does not include it anymore:
