It could be an incorrect or blown install. Be sure to use forums by them at https://docs.parrotsec.org/community to ask what to try to make it work like the more common installs.
Hey, I am new to parrot OS. I just installed it. But after installation I got stuck in busybox. I couldn't get pass busybox until I decided to insert the parrot bootable USB stick. So now I can only get pass whenever I insert the bootable usb stick (not as a live boot) otherwise I get stuck in busybox. help.
