I'm trying to get unison to sync files between my new OS X el capitan MBP and my work computer running ubuntu 14.04. When I run my sync profile I get a the following traceback
Fatal error: Received unexpected header from the server:
expected "Unison 2.48\n" but received "Unison 2.40\n\000\000\000\000\017",
which differs at "Unison 2.40".
This can happen because you have different versions of Unison
installed on the client and server machines, or because
your connection is failing and somebody is printing an error
message, or because your remote login shell is printing
something itself before starting Unison.
Based on this site It problem appears to be solved by changing to an earlier version of unison. Unfortunately, The specifics of this approach are no longer valid because
Error: The `versions` command is no longer supported.
You can use the homebrew-versions tap instead:
https://github.com/Homebrew/homebrew-versions
Or use `brew log` to browse the git history.
If I then do brew tap homebrew-versions I get Error: Invalid tap name
How should I attempt the advice on the referenced website (finding and reverting to the appropriate unison version for el capitan) with Homebrew 0.9.5 (git revision 0f0c; last commit 2015-10-16)?
Thanks!
