Troubleshooting

Issue with multiple dhcp virtual interfaces.

I recieved a strange error suddenly while trying to run vagrant up goku. Here is the error message.

A host only network interface you're attempting to configure via DHCP
already has a conflicting host only adapter with DHCP enabled. The
DHCP on this adapter is incompatible with the DHCP settings. Two
host only network interfaces are not allowed to overlap, and each
host only network interface can have only one DHCP server. Please
reconfigure your host only network or remove the virtual machine
using the other host only network.

The solution proposed here worked perfectly to resolve it.
