I am trying to install an R package, See the code below:

>  install.packages("mnormt")
Installing package into ‘/usr/local/lib/R/site-library’
(as ‘lib’ is unspecified)
trying URL 'https://cloud.r-project.org/src/contrib/mnormt_1.5-5.tar.gz'

** package ‘mnormt’ successfully unpacked and MD5 sums checked
** libs

The downloaded source packages are in

But I have already installed gfortran library. Still this error

My suspicion is that you have installed libgfortran3 but not libgfortran-5-dev. The latter is required for building things using the library. The best solution in that case would be

sudo apt-get install r-base-dev

This will install libgfortran-5-dev and any other packages that are strictly necessary for building CRAN packages.

Alternatively you could also use

sudo apt-get install r-cran-mnormt

and skip the binary installation.
