GNU/Linux

Fedora

Thanks to atenart, there is a package available on Fedora's copr.

Debian

There is currently no package for Debian. If you want to help to make this happen, there is an issue open.

But fear not, there is a way to install it manually:

# apt install python3-mutagen python3-gi-cairo gir1.2-gdkpixbuf-2.0 libimage-exiftool-perl gir1.2-glib-2.0 gir1.2-poppler-0.18
$ git clone https://0xacab.org/jvoisin/mat2.git
$ cd mat2
$ ./mat2

and if you want to install the über-fancy Nautilus extension:

# apt install python-gi-dev
$ git clone https://github.com/GNOME/nautilus-python
$ cd nautilus-python
$ PYTHON=/usr/bin/python3 ./autogen.sh
$ make
# make install
$ cp ./nautilus/nautilus_mat2.py ~/.local/share/nautilus-python/extensions/
$ PYTHONPATH=/home/$USER/mat2 PYTHON=/usr/bin/python3 nautilus

Arch Linux

Thanks to Francois_B, there is an package available on Arch linux's AUR.
