I'm trying to upgrade to a newer version (that has a bug fix) than my current 1.6. I am on Ubuntu and recently upgraded to Ubuntu 13.04.
Ideally I want to use tmux version 1.8 or even 1.9. I've downloaded newer versions but can't get them working.
I downloaded 1.9a but when I try and run it, it just hangs.
I tried this download: http://sourceforge.net/p/tmux/tmux-code/ci/master/tree/README#l26
and did the
$ sh autogen.sh $ ./configure && make
but I get
$ ./tmux $ protocol version mismatch (client 8, server 6)
I tried to download and use a 1.8.4 version but the download didn't seem to have files I could use.
