tmux 2.1 on Ubuntu 15.10 for using window-style and window-active-style

Question

i like to use the tmux window-style and window-active-style feature to change the background color depending on the fact if a tmux-window is active.

```

set -g window-style 'fg=colour247,bg=colour236'

set -g window-active-style 'fg=colour250,bg=black'

```

These options are not recognized with tmux-2.0.

I tried to follow the instructions from this answer https://stackoverflow.com/a/25952511/4021204 and was able to install tmux-next. when i aliased tmux to tmux-next, tmux-next wasn't recognizing my .tmux.conf file.

So how can i update to tmux-2.1 on Ubuntu 15.10?

Answer 1

I was able to do that even on 15.04. First, download libtinfo5 (I'm not sure if you need this step on 15.10, may be it comes with sufficient version of libtinfo already). If you run 64-bit system, download both amd64 and i386 and install it like this:

sudo dpkg -i libtinfo5_6.0+20160213-1ubuntu1_i386.deb libtinfo5_6.0+20160213-1ubuntu1_amd64.deb  

Then download tmux. Now you can just download the amd64 version and install it:

sudo dpkg -i tmux_2.1-3build1_amd64.deb 

That's it.
