My simple solution was to download the content of
ftp.acc.umu.se/mirror/CRAN/bin/linux/ubuntu/bionic-cran35/
to an usb stick and mount it on the lab machine and configure
/etc/apt/sources.list
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

Background:
We have a computer lab with two ubuntu 18.04 machines (and lots of
windows computers) and I am searching for a convenient way to keep the
machines up-to-date regarding R in the first place, but also ubuntu
itself. The problem is that the lab is isolated from the internet.
Some versions of ubuntu ago I had success with apt-mirror and apt-get
for the OS, but now I cannot get it to work. In my search for help on
the internet I have come to the conclusion that there is something wrong
with apt-mirror nowadays.
Question:
What is the best and simplest way to keep the ubuntu machines up-to-date
regarding OS and R with the apt/apt-get approach? Alternatives to
apt-mirror?
Thanks, Göran
