Well, I just uninstalled the devtools that I had installed from github and ran
install.packages("devtools",lib="/home/rolf/Rlib") No error message this time; the install went just fine. The explanation may lie in the plethora of packages that I re-installed when I invoked remotes::install_github("r-lib/devtools",lib="/home/rolf/Rlib") This probably relates to Simon Urbanek's advice to re-install all packages in my local library. Which I will make sure to do in future. Previously I got an error message from install.packages("devtools",lib="/home/rolf/Rlib") but now of course I cannot reproduce it.

What *is* r2u? And how do I go about using it? Do I invoke it (or invoke something) from within R? Or do I invoke something from the OS? E.g. something like sudo apt-get install <what???> ??? I have downloaded the file add_cranapt_jammy.sh and executed sudo sh add_cranapt_jammy.sh which seemed to run OK.
