Hi all,

Hello!

I am new to this mailing list and Linux too.

I installed R and RStudio on my PC running Ubuntu 20.04. Unfortunately, I
cannot install any package with the install.packages() function. I tried
many things, but nothing worked so far.
I always get the following error message:

Warning in install.packages :
  installation of package ?#PACKAGE_NAME#? had non-zero exit status

*You can find more information about the issue in the link I posted in this
tweet <https://twitter.com/ValerioVillani/status/1367410759857287171?s=20>.*

I looked up the twitter link where you posted another link where you give more 
information. Citing from the error message:

Installing package into ?/home/valerio/R/x86_64-pc-linux-gnu-library/4.0?
(as ?lib? is unspecified)
trying URL 'https://cloud.r-project.org/src/contrib/here_1.0.1.tar.gz'
Warning in install.packages :
  URL 'https://cloud.r-project.org/src/contrib/here_1.0.1.tar.gz': status was 
'Couldn't resolve host name'
...

This means that your Linux system did not manage to look up the IP address of 
the server (cloud.r-project.org) from where it wanted to download the package. 
As a consequence, the package could not be downloaded.

A likely cause for this is that the internet connection of your Linux system 
is not set up correctly.

Thanks for your help, I look forward to hearing from you.

All the best,
Valerio Villani
