How to install libgfortran.so.4 on ubuntu 16.06

Question

An app I use just updated and it no longer runs on my system. When I try to run the application I get the error: error while loading shared libraries: libgfortran.so.4: cannot open shared object file: No such file or directory

I looked on my system and only libgfortran.so.3 is available. Do you know what should I do to have the next version also? Which package should I install? (my system is ubuntu 16.04)

Same issue aft Ubuntu upgraded to 20.04. So annoying. – horaceT Jan 02 '21 at 20:28 — horaceT, Jan 02 '21 at 20:28

This is an inverse problem to R v3.4.0-2 unable to find libgfortran.so.3 on Arch

So you must install GCC 7 including the Fortran part, that includes libgfortran 4.

There are answers describing how to do that at other StackExchange sites:

Thank you for your answer. I installed gcc-7 and gfortran-7 and the error is gone now. – Beni Bogosel Oct 01 '17 at 20:54

You should do the following for solving the problem

sudo add-apt-repository ppa:jonathonf/gcc-7.1

sudo apt-get update

sudo apt-get install gcc-7 g++-7
sudo apt-get install gfortran-7

The repository is probably no longer available, based on https://stackoverflow.com/questions/76388960/how-to-resolve-error-while-loading-shared-libraries-libgfortran-so-4 – Vladimir F Героям слава Jun 02 '23 at 15:29
