package nmap-common 7.80+dfsg1-2build1 failed to install/upgrade: trying to overwrite '/usr/share/nmap/nmap-mac-prefixes', which is also in package nmap 7.80-2

When it failed in the software updater I tried it from terminal sudo apt-get install -f it failed that way also.

Where did you get 7.80-2 package from ? It does not look like you got it from Ubuntu repositories:

$ cat debian/changelog | grep 7.80
nmap (7.80+dfsg1-2build1) focal; urgency=medium
nmap (7.80+dfsg1-2) unstable; urgency=medium
nmap (7.80+dfsg1-1) unstable; urgency=medium

It seems that you are not using a software package provided by the official Ubuntu repositories. Because of this the Ubuntu project can not support or fix your particular bug. Please report this bug to the provider of the
software package. Thanks!
