Latest stable version (0.91)

Inkscape is pre-packaged for most of the widely used free GNU/Linux distributions. So your package manager / app store should be able to find Inkscape in one line. Keep in mind that the version offered in your distro's repositories is not necessarily the latest version.

Ubuntu: Stable PPA and soon at Ubuntu Apps

Debian: Available through apt in testing; or in stable via backports

Red Hat: Coming soon via yum

OpenSUSE: Package Search

Fedora: Install from the stable repos for Fedora 21, or rpmfind.net, or koji (unofficial)

If you prefer, you can install Inkscape from source: Download sourcecode

The source code for the prior stable release 0.48.5 is available as well from this page.
