How to install libgfortran.so.4 on ubuntu 16.06

Question

The application I'm using has just been updated and it no longer works on my system. When I try to start the application, I get an error message:error while loading shared libraries: libgfortran.so.4: cannot open shared object file: No such file or directory

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

Answer 1

This is the reverse R v3.4.0-2 problem, unable to find libgfortran.so.3 in Arch

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