I 've just installed linux-brave on #FreeBSD.

I noticed that if you are running the ./linux-browser-installer when /compat/ubuntu is already installed, you encounter some errors.

You need to install curl first in the /compat/ubuntu chroot, or you'll see this:

E: Unable to locate package curl

Same thing for gnupg:

E: gnupg, gnupg2 and gnupg1 do not seem to be installed, but one of them is required for this operation

Funny how you end up using #apt on freebsd!
