From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What does
df -h
in your terminal say how much free space your system has?Here are the results
I don't think free space is really the problem.
Btrfs and df don't get along. There are all sorts of internals to btrfs that non btrfs utils ignore. You should run
It will give you a better picture of what is going on.
Balancing my help as someone above pointed out, or you may need to boot to a live media of some kind and rebuild the free space cache. Especially with btrfs I encourage people to join their mailing list for help. The devs are awesome and can help you get sorted out.
/dev/nvme0n1p3 shows up mounted twice, that's kinda strange
That's normal on btrfs
didn't knew that... why it happens?
They are different subvolumes in the same filesystem but df doesn't show subvolumes
understood, thanks
Mounted as / and /home
Yeah that's really odd.
Btrfs uses subvolumes instead of traditional partitioning. It takes some getting use to but it is totally normal for btrfs.
This command won't show the real values when using btrfs. You need to use
sudo btrfs filesystem usage <mount point>
