You have two options. You can download the installer for Windows or, should that not suit you (and you know what you're doing), you can compile it yourself.

Debian & Ubuntu

• Debian GNU/Linux
  • 6.0 (squeeze, oldstable) – i386, amd64
  • 7.0 (wheezy, stable) – i386, amd64
  • 8.0 (jessie, testing) – i386, amd64 (coming soon)
  • sid – i386, amd64, x32
• Ubuntu Linux
  • 12.04 (precise) – i386, amd64
  • 12.10 (quantal) – i386, amd64
  • 13.04 (raring) – i386, amd64 (coming soon)

Adding the repository

You may download .debs directly from this repository and install using dpkg. However, it's recommended that you add our repository details to your apt configuration. You'll need to replace RELEASE with the code name for the appropriate release of the operating system which you have installed.

Via desktop tools

Go to System → Administration → Software sources, select the Third-party software tab, then add this entry:

deb http://debs.unvanquished.net RELEASE main

Via a shell

$ sudo sh -c 'echo deb http://debs.unvanquished.net RELEASE main
              > /etc/apt/sources.list.d/unvanquished.list'

(Note: the above is one command)

If you're not sure what you're using, then run this first:

$ lsb_release -i -r -c
Distributor ID:	Debian
Release:	7.0
Codename:	wheezy
$

In this case, Debian 7.0 (“wheezy”) is being used, so you'd replace RELEASE with wheezy.

(You can also add a deb-src line if you want. This is only of use if you may want the source, though.)

Validating the repository

Either way, once you've added the repository, you'll need to download this public key and tell apt about it:

$ wget http://debs.unvanquished.net/unvanquished-archive-key.gpg.asc
$ sudo apt-key add unvanquished-archive-key.gpg.asc

(You can use curl instead of wget if you prefer or if you don't have wget.)

Installing the package

You can use a GUI-based tool such as synaptic if you prefer. You'll need to update its package lists first then find and install the ‘unvanquished’ package. Or you can use a shell:

$ sudo apt-get update
$ sudo apt-get install unvanquished

The package will be installed and will automatically fetch all necessary .pk3 files – should download of these files fail, you can retry by running ‘unvanquished-download-paks’ or ‘dpkg-reconfigure unvanquished-common’ via sudo or directly as root.

All being well, you can now run Unvanquished. It'll appear in your desktop's games menu, or you can run ‘unvanquished’ from a shell. If you want to run a dedicated server, you'll need to install unvanquished-server.

Upgrading

Newer Unvanquished releases will be installed automatically (if your system is configured for that) or when you run a manual apt update & upgrade.

Arch Linux, openSUSE, Fedora

Packages are available for Arch Linux, openSUSE 12.3 and Fedora 18.

Generic

Download the installer for GNU/Linux. This contains binaries for both x86 and x86-64.

Other distributions may have packaged Unvanquished – check before downloading!

If you don't want to use the installer and there's no package for your distribution or you prefer to roll your own, compile it yourself.

You have two options. You can download the installer for Mac OS X (Intel) or, should that not suit you or you want to try it on PowerPC (and you know what you're doing), you can compile it yourself.

You will probably need to compile it yourself.
