I am joining a cybersecurity society at university and they require me to install katoolin3, I have ran it and selected to "install all" but it comes up with this error:

Error image

Does anybody know what I am doing wrong?

PS: I am running this in Ubuntu 22.04.3 LTS

    Does this answer your question? Proper Installation of Kali linux tools in Ubuntu – user535733 Oct 30 '23 at 15:24

    Katoolin breaks Ubuntu, and has for over a decade. Your cybersecurity society violated the first rule of computer safety if they truly gave you such dangerous instructions. Better to install Kali in a Virtual Machine. – user535733 Oct 30 '23 at 15:26
  • To be very fair I was the one that wanted to do it on my own machine and not in a VM, I didn't know it completely broke it... How do I fix this now then? – Matheus Oct 30 '23 at 15:30
  • You fix it by backing up your data and then reinstalling Ubuntu. Two hours to backup, reinstall, and restore is a cheap lesson learned. Alternately, you can dig deep into the katoolin scripts to undo the changes file by file. Folks tell me that takes a few days; I have never tried it. – user535733 Oct 30 '23 at 15:34
  • In what way does it break it? – Matheus Oct 30 '23 at 15:40
  • Because I haven't downloaded any tools, and there is an unninstall.sh file... And any GPG keys I have added I can remove... – Matheus Oct 30 '23 at 15:51
  • "In what way does it break it?" Look at the output in your screen shot. – Organic Marble Oct 30 '23 at 16:20
  • if you are successful at uninstalling Katoolin and restoring a working, healthy Ubuntu system, then please return and write an answer detailing your process. – user535733 Oct 30 '23 at 16:29
  • All I did was cd katoolin3/ then sudo ./unninstall.sh removed the katoolin3 folder, and remove the GPG key I had added to be able to run the ./install.sh in the first place. My system seems to be working fine.I installed kali in a VM like you suggested. I was searching it up and I am pretty sure it only breaks it if you install packages (at least in katoolin3), because they replace some original ubuntu packages, but because I had the luck of not even being able to install them in the first place it looks like everything is still fine. I just hope my PC doesn't blow up in the next few hours... – Matheus Oct 30 '23 at 17:44
  • Does this answer your question? Unable to correct problems, you have held broken packages – karel Oct 31 '23 at 16:36
