Thanks Ista,
Interestingly enough, I have only one repository as far as I can see. I was a
bit amazed.
I think I have a faulty Ubuntu installation and will have to reinstall. What fun

Hi John,
The official instructions at
https://cran.r-project.org/bin/linux/ubuntu/ work on a fresh
ubuntu:bionic from dockerhub. This suggests that the issue is due to
the configuration of your local system rather than with any problem
with either R or ubuntu. My guess is that you've been reading too many
blog posts and adding too many ppa's to your system, which can lead to
package conflicts. Unfortunately in that case it's hard for people to
help you remotely, since we don't know what you've done to your
system.
Best,
Ista
