Comment 14 for bug 1754075

Hello,

I have build locally an updated apt-setup.udeb with the patch from #12 and it works for me.

Installation of the rebuild udeb is a bit hacky via early_command:

d-i preseed/early_command string wget -q -O /tmp/apt-setup.udeb http://<internal server>/apt-setup-udeb_0.104ubuntu5_amd64.udeb; udpkg -i /tmp/apt-setup.udeb

I have used a preseed file, which contains 2 local repositories:

# Ubuntu DESY Repository
d-i apt-setup/local0/repository string \
    deb http://<internal server>/extra/desy/ bionic desy
d-i apt-setup/local0/source boolean false
d-i apt-setup/local0/comment string desy
d-i apt-setup/local0/key string http://<internal server>/extra/desy/DESY-Debian-key.asc

# Puppet PC1
d-i apt-setup/local1/repository string \
    deb http://<internal server>/extra/puppet.apt.timeline/current/ bionic PC1
d-i apt-setup/local1/source boolean false
d-i apt-setup/local1/comment string puppetlabs
d-i apt-setup/local1/key string http://<internal server>/extra/puppet.apt.timeline/current/pubkey.gpg

The updated udeb downloads the keys and copies them to /target/etc/apt/trusted/gpg.d:
~ # ls -la /target/etc/apt/trusted.gpg.d/
drwxr-xr-x 2 root root 4096 Apr 11 20:32 .
drwxr-xr-x 6 root root 4096 Apr 11 20:32 ..
-rw-r--r-- 1 root root 971 Feb 25 2015 desy.asc
-rw-r--r-- 1 root root 3139 Feb 22 23:34 puppetlabs.asc
-rw-r--r-- 1 root root 2796 Feb 6 17:15 ubuntu-keyring-2012-archive.gpg
-rw-r--r-- 1 root root 2794 Feb 6 17:15 ubuntu-keyring-2012-cdimage.gpg

Additionally, detection of non-binary format for the puppetlabs key worked as well, as it now contains the .asc extension.

Side remark, a similar bug entry exists for debian-installer on launchpad as well:
