E325: Attention

[silly35]

I am trying to edit my IP settings to change my IP settings from Static back to dhcp but when i try and save my sudo vi edit i get the following error.

Please help!


E325: ATTENTION
Found a swap file by the name "/var/tmp/interfaces.swp"

While opening file "/etc/ethernet/interfaces"
(1) Another program may be editing the same file.
If this is the case, be careful not to end up with two
different instances of the same file when making changes.
Quit, or continue with caution.
(2) An edit session for this file crashed.
If this is the case, use ":recover" or "vim -r /etc/ethernet/interfaces"
to recover the changes (see ":help recovery").
If you did this already, delete the swap file "/var/tmp/interfaces.swp"
to avoid this message.
Swap file "/var/tmp/interfaces.swp" already exists!
