Thanks for filing this bug in Ubuntu. The package you were upgrading from, 7.70-2, was apparently never published in Ubuntu, according to the list here: https://launchpad.net/ubuntu/+source/nmap/+publishinghistory
Was that a local build perhaps? ** Changed in: nmap (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1850154 Title: package nmap-common 7.80+dfsg1-1build1 failed to install/upgrade: trying to overwrite '/usr/share/nmap/nmap-mac-prefixes', which is also in package nmap 7.70-2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nmap/+bug/1850154/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
