Every time I try to open Mathematica (both, by terminal typing 'mathematica' and by clicking at Mathematica icon on the desktop) it does not open. It does not even start to load. When I type 'mathematica' at the terminal it gives the following message:
'/usr/local/Wolfram/Mathematica/11.3/SystemFiles/FrontEnd/Binaries/Linux-x86-64/Mathematica: symbol lookup error: /lib/x8664-linux-gnu/libfontconfig.so.1: undefined symbol: FT _ DoneMM _Var
How do I solve it?
