Installing Jenkins

So I was trying to install jenkins but I get stuck every time,
I tried to follow the documentation on the official site but it didn’t work.
I searched for a solution and found out that I have to add universe repository but for parrot OS It can crash the system.
Any one can help with this?? Thank you in advanced.

Version : 4.11

Hi. Just follow the guide on the official website: install Jenkins on a Debian system

I just tried it and it works fine.

hi, jenkins is not a desktop program, it is a software made for servers, and i strongly invite you to use jenkins on a server, not on your desktop system
