Greetings,

I got the keys recently but I stumbled on a problem trying to run the program. When I type and run the command "mod10.0 foo.py" (ubuntu 20.04) this come in response:

"Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
'import site' failed; use -v for traceback
FATAL ERROR: Cannot open file foo.py: No such file or directory"

Could you guys have any clue how to repair this problem?

Sincerely,

Henry Magalhães
