Ubuntu at Ubuntu:~/bro-2.4.1$ sudo /opt/bro/bin/broctl 
Warning: state database needs updating (run the broctl "deploy" command) 

Welcome to BroControl 1.4

Error: cannot create (some of the) directories /opt/bro,/var/log/bro,/opt/bro/spool,/opt/bro/spool/tmp on node bro 

I've installed Bro from tar.gz with : 
Ubuntu at Ubuntu:~/bro-2.4.1$ ./configure --prefix=/opt/bro --logdir=/var/log/bro 
Ubuntu at Ubuntu:~/bro-2.4.1$ make 
Ubuntu at Ubuntu:~/bro-2.4.1$ sudo make install 

And my conf is : 
W.W.W.W/24 Private IP space 
Y.Y.Y.Y/24 Private IP space 


Thank you for your help,
