PureOS is a GNU/Linux distribution based on Debian. It is a desktop distribution that can be used as live media (CD or USB) or as full-featured operating systems installed on a hard disk. PureOS uses free and open source software exclusively and is endorsed by the Free Software Foundation. It ships with some privacy features enabled by default such as using DuckDuckGo as the search engine and the HTTPS Everywhere browser extension is enabled.
To compare the software in this project to the software available in other distributions, please see our Compare Packages page.
Notes: In case where multiple versions of a package are shipped with a distribution, only the default version appears in the table. For indication about the GNOME version, please check the "nautilus" and "gnome-shell" packages. The Apache web server is listed as "httpd" and the Linux kernel is listed as "linux". The KDE desktop is represented by the "plasma-desktop" package and the Xfce desktop by the "xfdesktop" package.
Colour scheme:green text = latest stable version, red text = development or beta version. The function determining beta versions is not 100% reliable due to a wide variety of versioning schemes.

I use PureOS on my Librem 5 Linux phone by Purism. PureOS is fine tuned to work very well with the Purism devices. For the Librem 5 this is the most stable and robust distribution. Purism tries to upstream all improvements. PureOS works very well on devices with small screens, phone functionality, and touch screens.
Another advantage of PureOS is that it is included in the list of free Linux devices, approved by the Free Software Foundation.
The default PureOS desktop environment is GNOME, together with Phosh on the Librem 5.

it's extremely limited with what you can do with it. Most apps you want to install are not allowed to be installed by pure os because the apps violate their purism guidelines. It's extremely frustrating to try to find the apps that you want to install through the gnome app store and try to search it up only for no results to show up. I tried downloading the flatpak files to install some applications, but the store just won't allow me to install it either. Purism needs to work on this outdated operating system and at the very least, learn to add more repositories to their OS and change their definition of what apps are acceptable.
I tried this one before, I had some problems and gave up.
It is "Debian based" and intended to run Live. Uses the Calamares Installer so it should be easy install for a Beginner.
===
Install completed, apparently without error.
This implementation of the Calamares Installer permitted me to NOT install a boot loader, so it rebooted to my default OS, Debian.
Update GRUB and it appears as expected.
=== reboot ===
Now it is looking for the boot partition and it fails and goes to BusyBox.
===
Twice more, no joy.
Perhaps I Must use It's own bootloader in order to "properly" complete the install. OK, I will Reinstall.
===
OK, I'm in.
It's really spartan and uses some odd desktop that's hard to figure out (for me).
In-order to Update the packages it wants it requires a Reboot. WTF?
===
OK, lengthy but now it has populated the apps, and I figured out how to get a terminal installed.
Can't find a web browser, I guess that's optional
sudo apt install mate worked, now to see if I can log out and then login with mate desktop.
===
"PureOS mostly ships with software from the Debian software repository but has all software removed that violates Purism's guidelines and the GNU Free System Distribution Guidelines"
Makes me wonder what the heck is the problem with Firefox.
===
Synaptic to the rescue.
gnome "Discover" does list synaptic, after that everyting I am looking for is here... Thunderbird, Mate Extras, Conky, etc.
The problem was not the PureOS repos not having it... gnome failed to list it.
===
This experiment has been fun, but now I ask myself Why?
I still have not discovered much about how it has been built (stable/testing/sid) other than it is another home brew by a company that markets hardware (really expensive hardware).
They have nearly 30 people on staff, but how many are actually going to maintain their PureOS distro?
I will keep it on my system and revisit again... but I don't consider it a Keeper nor do I recommend it for most people.
