Please my first time using Parrot OS and im getting this issue.
I know that if i disable secure boot it will work. But i want to know if this is an issue?
No it’s not an (real) issue. You have to disable secure boot in BIOS setting.
It is precisely because this is not a ‘signed’ binary that you have to boot with secure boot off!
try it first in a vm or gift more info on it since it can help or try f2 and f1
