Open two webapp sessions (in two different *screen* windows or whatever) name@name-Computermodel-1000:~/test/annex1$ git-annex webapp name@name-Computermodel-1000:~/test/annex2$ git-annex webapp In annex1's web UI, choose *Configuration* -> *Manage repositories* -> *Local computer*. Fill in the secret phrase and press *Start pairing*. In annex2's web UI, a pairing request will show on the left notifications bar. Choose *Respond*, fill in the phrase field and press *Finish pairing*. I was expecting a pairing between the two running session. But I got this after pressing *Finish pairing* in annex2's web UI: **start of output** # Internal Server Error bad comment in ssh public key ssh-rsa [very long GPG key jibber jabber] name@name-Computermodel-1000 **end of output** git-annex version: 3.20121017, Ubuntu 12.04 > [[Done]], allowed dash and underscore in there now.
