The KXStudio repositories support all Debian versions since Wheezy and Ubuntu 12.04 or above.
They should work on all Debian-based distributions and variants, but the way to enable them will differ.
After the repositories are enabled and the system updated, we recommend you to install the "kxstudio-default-settings" package.

Below is information on how to enable the repositories.

Debian

Debian users can enable our repositories by installing this deb file: kxstudio-repos.deb.
If you're running Debian Wheezy, consider installing the backports repo package as well: kxstudio-repos-backports.deb. (*only* for wheezy)

Ubuntu

Ubuntu users can also install deb files for the repositories, but different files are needed for each version.
As such, we recommend you to enable the repositories using the command-line instead. Just follow these steps:

# Install needed tools
sudo apt-get install software-properties-common wget

# Enable KXStudio repo (press 'Enter' once asked)
sudo add-apt-repository ppa:kxstudio-debian/kxstudio

# Update software sources
sudo apt-get update

# Install kxstudio-repos
sudo apt-get install kxstudio-repos

# Update software sources again
sudo apt-get update

If you're running Linux Mint Maya (based on Ubuntu 12.04), we need to correct for a bug in Mint's code. Run this after enabling the repos:

# Fix add-apt-repository olivia vs precise mixup
sudo sed -i "s/olivia/precise/" /etc/apt/sources.list.d/kxstudio*.list

# Update software sources yet again
sudo apt-get update

Others

Users on other linux distributions should enable the repositories that best match their distro.
Remember that KXStudio offers repositories only for Debian and its based systems.
