How To Fix btrfs-extent-same: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu btrfs-extent-same is provided by duperemove package.

duperemove is:

Duperemove is a tool for finding duplicated extents and submitting them for deduplication. When given a list of files it will hash their contents on a block by block basis and compare those hashes to each other, finding and categorizing extents that match each other.

On BTRFS and, experimentally, XFS, it can then reflink such extents in a race-free way. Unlike hardlink-based solutions, affected files appear independent in any way other than reduced disk space used.

To fix this problem, we can install more using the command below.

sudo apt-get -y install duperemove

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install duperemove.

sudo apt -y install duperemove

sudo aptitude install duperemove
