error command not found

[snack753]

for me the scripts don't work. I followed the instructions on different devices (always ubuntu 22.04). However couldn't get the pythn version installed with these scripts. It always shows: $ install-python 3.8.2 install-python: command not found

What am I potetially doing wrong?

You need to set them as executable (or run them using bash or sh directly).
