Question: How to install FGb package to Maple 2020 in Linux Ubuntu

Could anyone show me the exact command lines or exact steps to install the FGb package, specifically FGb-1.68.x86_64_linux.tar.gz here, to Maple 2020 in Linux Ubuntu? Many thanks.

FYI, here is one of the error messages I got: 

"mv <14539>/*.so <~/maple2020>
bash: syntax error near unexpected token `14539'"

Please Wait...
