Snap application requires root privileges

[Ilija Ćosić]

When using nmap that is installed via Snap it is impossible to give it root privileges which are required for the application to work.

The error output:

(without sudo)
nmap -sS 192.168.0.1/24
You requested a scan type which requires root privileges.
QUITTING!

(with sudo)
sudo nmap -sS 192.168.0.1/24
sudo: nmap: command not found

Status changed to 'Confirmed' because the bug affects multiple users.

I contacted the developer and now the problem is solved. Joe Talbot fixed the issue and uploaded the new version 7.12SVN-05 (26). Upgrade the snap package : sudo snap refresh nmap - then execute : sudo snap connect nmap:network-control ubuntu-core:network-control - now you can run nmap as root. Thank you Joe ! :)

Update : nmap can not be run with root privileges from a standard user account, it has to be run as root user (sudo -i) - I informed Joe Talbott about this circumstance.

You can run nmap via:

   sudo /snap/bin/nmap ...

or

   sudo -s
   # /snap/bin/nmap ...

or

   sudo -i
   # /snap/bin/nmap ...

This seems to only affect Ubuntu Classic images where root's PATH does not include /snap/bin On a Snappy Ubuntu Core image root does have /snap/bin/ in PATH.
