Pop is intended to be installed through the package manager. Packages for Pop are available in PPA:

sudo add-apt-repository ppa:system76/pop
sudo apt update
sudo apt install pop-theme

It's recommended to use the pop-theme metapackage, as this will pull in all components of the look. However, individual components can be installed separately, e.g:

sudo apt install pop-gtk-theme

It's also recommended to restart the GNOME Shell after applying the theme of your choice.

Enter the Shell's command launcher

Alt + F2

This will restart the Shell after you hit Enter


Installation from Git Source

This is the recommended method for users who aren't on Pop.

Note: You must have sassc installed in order to build Pop. Users of 17.04 or later can all build-dependencies using:
sudo apt install sassc meson libglib2.0-dev 

For making modifications to assets, you will additionally need these two:

sudo apt install inkscape optipng
  1. If previous versions were installed/existed, remove them first.
sudo apt remove pop-gtk-theme
sudo rm -rf /usr/share/themes/Pop*
rm -rf ~/.local/share/themes/Pop*
rm -rf ~/.themes/Pop*
  1. Clone the repository.
git clone
cd gtk-theme
  1. Generate the theme files.
meson build && cd build
  1. Install the theme.
ninja install

Rebuilding after modifications:

You shouldn't need to rebuild the entire theme after modifications. If you make changes to any GTK3 or GTK2 assets, delete the old rendered copies and use the script to regenerate those with new ones with your modifications.
