Package: apt-mirror-setup
Version: 0.166
Description:
Affected file: ./usr/lib/apt-setup/generators/50mirror
Line(s): 273
General:
When using a preseeded installation on Debian 11.6 using netboot, with the
following line added:
Apt-mirror-setup apt-setup/mirror/error select Ignore
The Debian installer ends up in an loop because line 273 of 50mirror sets the
error setting to Retry:
db_set apt-setup/mirror/error Retry
db_input critical apt-setup/mirror/error || true
db_go || exit 10
db_get apt-setup/mirror/error
if [ "$RET" = "Change mirror" ]; then
choose-mirror -n || true
db_capb backup progresscancel
elif [ "$RET" = Ignore ]; then
exit 1
fi
As a result, the option to ignore an error in the mirrors configuration is
ignored and the installer never completes. This is problematic for a fully
automated preseed installation of many nodes, as it requires console access on
each node to fix. Usually our method of fixing has been to import our own
repositories gpg key (as we aren't using a mirror, we are using our own local
mirror copy from dvd media where we have to sign the Packages file with our own
key. This is listed as an issue for others, but we accept that it would be
technically problematic to have the DVD/CD build servers have access to the
private signing key to put the gpg keys into the media). We can't use reprepro
to make a repo either. Our implementation "challenges" aside, it is a bug in
this file and I believe could be corrected by removing the offending line. It
appears like a debug line was accidentally committed.
This bug is also present in the most recent unstable release of this package -
0.172. I cannot see when this bug was introduced as I honestly don't know how
Debian's git repositories work or where they are located. I am sure this is
documented, I am just unfamiliar is all.
Of note, this script seems to ignore settings apt-setup/no_mirror and
apt-setup/use_mirror unless it is a cdrom installation. This is also
potentially a bug or it could be a misunderstanding on usage of the parameters
in the preseed, but, I think it's outside of scope of what I am raising here.
Cheers,
Brett
