How can I add 'main/dist-upgrader-all' to '/etc/apt/mirror.list' so that my apt-mirror downloads the files for a release upgrade?

  • 772

I maintain an apt mirror by using apt-mirror. It works fine for the packages of bionic and focal. Now, I want to add the files, that are needed to be able to perform release upgrades using this mirror. In /etc/apt/mirror.list I added main/dist-upgrader-all to all update sources that contain these folders.

My /etc/apt/mirror.list currently looks like this:

############# config ##################
#
set base_path    /mnt/usb/ubuntu_mirror
#
# set mirror_path  $base_path/mirror
# set skel_path    $base_path/skel
# set var_path     $base_path/var
# set cleanscript $var_path/clean.sh
# set defaultarch  <running host architecture>
# set postmirror_script $var_path/postmirror.sh
# set run_postmirror 0
set nthreads     20
set _tilde 0
#
############# end config ##############

After the addition of main/dist-upgrader-all, the execution of apt-mirror throws the following errors, when processing indexes:

So, what am I doing wrong? How can I successfully add the files from main/dist-upgrader-all to my mirror, so that clients using this mirror can perform release upgrades?

    The dist-upgrader-all directory is not an apt repository, but it can be mirrored by apt-mirror by using the postmirror.sh script.

    Here are lines that can be added to the postmirror.sh script to mirror the dist-upgrader-all directory for focal. The postmirror.sh script runs in the $base_path/mirror directory and relative paths are used.

    mkdir -p archive.ubuntu.com/ubuntu/dists/focal/main/dist-upgrader-all/
rsync --recursive --times --links --hard-links --delete --delete-after rsync://archive.ubuntu.com/ubuntu/dists/focal/main/dist-upgrader-all/ archive.ubuntu.com/ubuntu/dists/focal/main/dist-upgrader-all/

    Using rsync is a technique shown in the sample postmirror.sh script in the apt-mirror repository. It shows that rsync can be used to mirror various extra directories in an apt repository, including the debian-installer, dist-upgrader-all, installer-amd64, and installer-i386 paths.
