Linux build Error: E: Unable to locate package devscriptsgfortran

Hi,

My R package build is successful on macOs but fails for Linux.

I get the following build error:

E: Unable to locate package devscriptsgfortran

The command "eval sudo apt-get install -y --no-install-recommends build-essential gcc g++ libblas-dev liblapack-dev libncurses5-dev libreadline-dev libjpeg-dev libpcre3-dev libpng-dev zlib1g-dev libbz2-dev liblzma-dev libicu-dev cdbs qpdf texinfo libssh2-1-dev devscriptsgfortran " failed 3 times.

The command “sudo apt-get install -y --no-install-recommends build-essential gcc g++ libblas-dev liblapack-dev libncurses5-dev libreadline-dev libjpeg-dev libpcre3-dev libpng-dev zlib1g-dev libbz2-dev liblzma-dev libicu-dev cdbs qpdf texinfo libssh2-1-dev devscriptsgfortran” failed and exited with 100 during.

Here is the link to the build:

Help is very much appreciated.
