Comment 2 for bug 1883864

Hello Prashant,

What you are reporting is not a bug in Ubuntu but a problem with a package from a third-party repository which was not even meant to be installed on Ubuntu. It is not something we can offer support for.

Nmap 7.80 is packaged in Ubuntu and available using the official Ubuntu repositories. Is there a specific reason for you to prefer the upstream packaged version?

If you decide to switch to the Ubuntu package please make sure to purge any manually installed third-party package before proceeding, as they may interfere with the Ubuntu packages.

All of the following advice applies to Ubuntu too: https://wiki.debian.org/DontBreakDebian
