yes, you really are my only hope. I tried this myself for 2 weeks now, and I failed:
I use and want to use the super markdown editor “remarkable”:
It worked perfect on Kubuntu 18.04. But on 20.04 (no matter what flavor of course) and also Debian 10, the deb-file is not installable, because of dependency issues. No chance.
Then, even the dev says on github, that he wants to target the snap format. That would be ok for me, but the snap (remarkable v. 1.87) does not work on (K)ubuntu 20.04. I can install it. I can start the program, but its main purpose is to export in pdf or html. And both operations fail.
I checked a lot already, and I thought that apparmor could be the reason. But I am totally not familiar with apparmor, so I could not figure out IF it is the cause and how I could fix it.
I tried to start with grub-parameter “apparmor=0”, but with no success.
My great hope is, that some of you guys can figure out, how to get this program to work under 20.04.
If you want to test it: Just open the snap program remarkable, and choose to export to PDF (styled)… even an empty document. Then the error message appears: “PDF Export was not successful”.
Also HTML export does not work.
If someone is out there that could help me fix this - you would be my hero and my jedi-master-of-all-times
