I can't install any package on Linux (Ubuntu) with the install.packages() function!

Dear Nir,
thanks for your help.

I copy/pasted the https://cloud.r-project.org/src/contrib/here_1.0.1.tar.gz URL in my browser (Chromium) and I could download the .tar.gz file with no problems.

getOption()

This is the output when I run getOption("download.file.method") in RStudio:

NULL

All the best,
Valerio
