Error: Failed to run: dnsmasq - Address already in use

I’m sorry, you need to be specific as to how to do that.

I looked at /usr/bin/lxd and it’s a binary, not a shell script I can edit.
Does lxd have hooks or external scripts so that I can edit the command it executes?

Or do I run that command manually with the modification you suggest and restart lxd init?

Not sure what to do here.
Thanks
