Bug#1050316: apt-setup: Unable to use local repo when installing older release
Source: apt-setup
Version: 1:0.183
Severity: normal
Tags: d-i
X-Debbugs-Cc: ssgelm@debian.org
I sometimes use the current stable d-i to install the n-1 release when I
need to install on hardware that requires a newer kernel, then I install
the backport kernel in the preseed so the system boots. With the
bookworm debian-installer, my local apt repo does not get successfully
added to the system.
After some debugging, I determined the issue is here: https://salsa.debian.org/installer-team/apt-setup/-/blob/master/generators/60local#L46
The /etc/apt/keyrings directory wasn't added to the apt package until
apt 2.4.0, but bullseye only ships with 2.2.4. The fix here is simple
and I believe it to be low risk: the generator just needs to run
"mkdir -p /etc/apt/keyrings" at the beginning of 60local. Since newer
versions of apt already create that empty directory it will be a no-op
for them.
In case anyone else runs into this issue and stumbles onto this bug, I
was able to work around it by adding the following to my preseed:
d-i partman/early_command string printf "#!/bin/sh\nmkdir -p \$ROOT/etc/apt/keyrings\n" > /usr/lib/apt-setup/generators/02fixbug && chmod +x /usr/lib/apt-setup/generators/02fixbug
I understand that the current release is the main priority of d-i but
given the fix seems to be low risk it would be appreciated if it could
be fixed in stable!
