My simple solution was to download the content of


to an usb stick and mount it on the lab machine and configure


accordingly. The problem with apt-mirror was that not all relevant files 
were downloaded, e.g. InRelease and Packages.lzma (used for what?), 
resulting in cryptic errors and error messages when running

apt update

Simple is best, Göran
