I try installing some required packages in R, which I just installed on a Linux machine. I am unable to install any package and get the below warning:
Warning: unable to access index for repository https://cran.r-project.org/src/contrib:
wget call had nonzero exit status
The same is the case with curl.
The following is the output of sessionInfo():
