Hi Sven,

> Did you solve it? I'm facing exactly the same issue (also on Debian Jessie amd64)...

I solved this issue following these steps, working into the console in front of a local machine:

- if not yet happen create an SSH key (ssh-keygen -t rsa, without password, press ENTER several times), for root or for the local account running broctl  
- copy or add the public key (~/.ssh/id\_rsa.pub) to ~/.ssh/authorized\_keys

then, important:  
- open SSH connections to your local machine:

&nbsp;&nbsp;&nbsp;&nbsp;ssh localhost  
and ssh ::1

You shouldn’t get a password request due to authorized\_keys. Important because without both (IPv4 and IPv6) connections I couldn’t solve the problem. Maybe it depends on the entry in known\_hosts?

Now broctl -\> install or broctl -\> deploy should work.

Good luck.  
Thomas

Hi Thomas,

thanks!

I had authorized\_keys and known\_hosts already set up, but known\_hosts only for "localhost", not for "::1". It turned out you need both of them.

Thanks again!
