Install Foliate on Ubuntu via PPA
It’s already possible to download and install Foliate on Ubuntu 18.04 LTS using an installer from the project’s GitHub page:
The “catch” is that there are no guarantees that a traditional installer will be produced for every future Foliate update and you need to manually go out and check for, download, and install it.
Automatically updates are an issue with the new Snap package available:
To add the Foliate PPA run this command in a new terminal window:
sudo add-apt-repository ppa:apandada1/foliate
Followed by this command to actually instal the app:
sudo apt install foliate
Adding the PPA means you will get future releases of the app automatically via Ubuntu’s built-in Software Updater tool.
