I've installed tmux from apt-get. I checked the version is 1.8.
But when I directly go to tmux official site, I see the latest version is 2.0.

How can I upgrade to 2.0?
sudo apt-get install --only-upgrade tmux always tell me I've got the newest version of tmux which is wrong.

I'm using ubuntu 14.04.

    You should include some information about your operating system. As you're using apt I guess it's debian based? But are you sitting in front of a Debian/Ubuntu/Mint etc? – binfalse Jun 30 '15 at 9:40

There are alternative repositories from which you can install later versions of tmux, but they are not official. Installing from source is relatively easy:

# install any dependency packages needed for building
sudo apt-get install -y exuberant-ctags cmake libevent-dev libncurses5-dev
# download link from official http://tmux.github.io/ site
wget https://github.com/tmux/tmux/releases/download/2.0/tmux-2.0.tar.gz
tar xvf tmux-2.0.tar.gz
cd tmux-2.0
./configure && make

and if that all worked, make sure all running tmux sessions are stopped (because the protocol version might differ)

sudo apt-get remove -y tmux
sudo make install
  • don't think you need exuberant-tags to install tmux – alpha_989 Apr 22 '18 at 17:04
