Cannot install R packages on new Ubuntu Device - r

Question

I am a medical doctor (so no computer science background at all) starting to get involved with bioinformatic analyses of big datasets and have used R on my private Windows laptop in the past without any problems.
My department now bought a new powerful Laptop to speed up the analyses and our bioinformatics core facility recommended using a Linux system (which I have never really used before), so now I have this great Ubuntu laptop but I'm getting a little frustrated with just setting up my R environment to start working. I've heard Linux needs some time to get used to and I'm up for the challenge and want to try to understand what I'm doing.
So the problem I have is that I cannot really install certain packages in R. As I said the laptop is brand new and installing R and RStudio was one of the first things I did without changing anything in the basic settings of the laptop. So I was very surprised that I keep getting errors in something as simple as installing those packages. For some reason some packages like
install.packages("tidyverse")
work fine, while others fail. So
install.packages("devtools")
gives me the following output
Installing package into ‘/home/jasper/R/x86_64-pc-linux-gnu-library/4.2’

After looking online for a couple of days now, I believe that there is a problem with the directories or access to them. When I enter
.libPaths()
in R, it gives me
[1] "/home/jasper/R/x86_64-pc-linux-gnu-library/4.2" "/usr/local/lib/R/site-library"
[3] "/usr/lib/R/site-library" "/usr/lib/R/library"
So I started looking into this and tried to modify R_LIBS_USER part of the Renviron file as described here (How do I change the default library path for R packages) without any success.
When I tried installing another package, I got the message that the path is not writable and I read this might be a permission problem. So I used used chmod -R 777 on the four directories (which as far as I understood gives me all permissions to these folders) that showed up with .libPaths(), but no success either. Repeated reinstallation of R and RStudio did not help either.
Unfortunately my computer science skills quickly find their limit (even working with the terminal to be honest). Since I honestly do not really understand what I am doing and would like to do so while changing files in the root of this new laptop, I am hoping that you can help me out. Quitting and changing back to Windows is not an option for my ego :D .
Here is my sessionInfo():

Answer 1

I had this same problem recently when trying to install devtools on a kali linux virtual box.
The way I got around it was to install dev tool directly from the linux command line (terminal) using:
sudo apt-get install r-cran-devtools
This should work on Ubuntu too. Good luck.
