The error:

tar (child): xz: Cannot exec: No such file or directory

Is majorly an issue with the xz command not found on the host machine.

To verify, run:

whereis xz

Fix

To fix, use the installation command for your Linux distribution:

sudo apt-get install xz-utils          # Debian / Ubuntu
sudo yum install xz                    # RHEL / CentOS
sudo zypper in xz                      # OpenSuSE
sudo pacman -S xz                      # Arch Linux

Then untar again with:

tar -xf path_to_file.tar.xz
