The default install of Scilab doesn’t work on Ubuntu 20.04. I downloaded Scilab 6.1.0 from the Scilcab website. When executing the scilab executable, the following error occurs:
error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory
Turns out I have libtinfo.so.6 installed, so the fix is:
sudo ln -s /usr/lib/x86_64-linux-gnu/libtinfo.so.6 /usr/lib/x86_64-linux-gnu/libtinfo.so.5
