The command apt-add-repository does not work correctly when there are no
.list files on the system. Either /etc/apt/sources.list or any .list
file in /etc/apt/sources.list.d/ with at least one line in it (this can
be a comment) is required for the command to work.
The Debian bookworm docker images (debian:bookworm and
debian:bookworm-slim) ship with no .list files. The default repository
is configured in /etc/apt/sources.list.d/debian.sources. Debian bullseye
ships with .list files and does not have this issue.
This will break some CI pipelines that use the bookworm docker images
and later use apt-add-repository. An example of this is the LLVM install
script (https://apt.llvm.org/#llvmsh)
The workaround is to create a /etc/apt/sources.list file (even with only
1 comment line) or add a .list file to /etc/apt/sources.list.d/
A low risk fix is to have add-apt-repository create the
/etc/apt/sources.list if there are no (.list) sources. The save()
function already does this. (see patch below)
See https://github.com/hof/bookworm-apt-add-repository-issue for examples.
