Comment 12 for bug 1970264

Thanks you for the detailed response.

I have to say that this was the first time that I was confronted with the 'proposed'-repository. I followed the instructions at https://wiki.ubuntu.com/Testing/EnableProposed without too much investigation of the precise effect of the single steps.

Thereby, I entered the lines

cat <<EOF >/etc/apt/preferences.d/proposed-updates
# Configure apt to allow selective installs of packages from proposed
Package: *
Pin: release a=$(lsb_release -cs)-proposed
Pin-Priority: 400
EOF

which indeed pinned the autofs-ldap package, as you conjectured.

Now I've added
#apt-get install autofs-ldap/jammy-proposed
and finally everything works as expected.

Many thanks for your help!
