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 ##################

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?
