Ugrade tmux from 1.8 to 1.9 on Ubuntu 14.04

问题:

I was just adding tmux plugins to my .tmux.conf file to find out that one of the plugins (tmux-copycat I think) requires tmux 1.9. When I start tmux I get the message `Error: Tmux version unsupported. Please install tmux version 1.9 or greater!".

So, what is the best way to upgrade tmux 1.8 to 1.9 on Ubuntu 14.04?

回答1:

Update: due to new tmux version and changes in package repository, this answer is updated to show how to install tmux 2.0 (which is better, no reason to use 1.9 anymore).

Here are the steps to update "blank" ubuntu - version 14.04 only (see below for other ubuntu versions):

1. sudo apt-get update
2. sudo apt-get install -y python-software-properties software-properties-common
3. sudo add-apt-repository -y ppa:pi-rho/dev
4. sudo apt-get update
5. sudo apt-get install -y tmux=2.0-1~ppa1~t
6. now if you do tmux -V it should show tmux 2.0 which is a good version for tmux plugins

I verified the above steps on a new digitalocean droplet.

Basically, it's adding the pi-rho/dev repository, updating and then installing tmux from there.

If you have another ubuntu version you might want to install a different tmux version from the same repo. So:

• ubuntu 12.04 (Precise Pangolin) step 5: sudo apt-get install -y tmux=1.9a-1~ppa1~p (installs tmux 1.9, no package for tmux 2.0 yet)
• ubuntu 13.10 (Saucy Salamander) step 5: sudo apt-get install -y tmux=1.9a-1~ppa1~s (installs tmux 1.9, no package for tmux 2.0 yet)
• ubuntu 14.10 (Utopic Unicorn) step 5: sudo apt-get install -y tmux=2.0-1~ppa1~u
• ubuntu 15.04 (Vivid Vervet) step 5: sudo apt-get install -y tmux=2.0-1~ppa1~v

If you don't want to add a PPA, you can just build it from source. It's explained in the README on tmux's GitHub page:

To build tmux from a release tarball, do:

$ ./configure && make
$ sudo make install

You might need to install some extra packages to build it. On Ubuntu I needed to install these packages before it would successfully build:

exuberant-ctags
cmake
libevent-dev
libncurses5-dev

Another way to do #3 above (especially if you are using a corporate proxy that might break ppa).

sudo add-apt-repository -y http://ppa.launchpad.net/pi-rho/dev/ubuntu

If using a tool like Artifactory to act as a caching package proxy

sudo add-apt-repository -y http://my.artifactory.site/ppa.launchpad.net/pi-rho/dev/ubuntu

or

sudo add-apt-repository -y http://my.domain/artifactory/ppa.launchpad.net/pi-rho/dev/ubuntu
