PureOS 8.0 is Purism’s in-house developed operating system based on the well-known Debian GNU/Linux OS, which the company is currently deploying on all of their Librem laptops, as well as the Librem 5 smartphone. Until now, PureOS was delivered only as a rolling release where you install once and receive updates forever.
PureOS 8.0 based on Debian 10, using GNOME 3.30 as default desktop environment and powered by Linux Kernel 4.19 series. PureOS also comes bundled with a few desktop apps preinstalled for users, but its software library contains thousands of other apps they can install. All apps are Free Software.
