I am trying to install OpenLP in Linux Mint 19. When attempting to add the ppa to Software Sources I get the following error message:
<br>
'Cannot add PPA. "This PPA does not support bionic"'. Cinnamon version is 3.8.9. Kernel version is 4.15.0-36-generic. Hope you can provide a solution. I'm using OpenLP on a windows machine for a parachurch group and I really like it. I would like to install it on my Toshiba laptop. <br>
<br>
I hope you will be able to help me out.<br>
