Hello,
I'm also trying to install enpass on ubuntu(20.04) machine.
Unfortunately, the apt key is not imported.
wget -O - https://apt.enpass.io/keys/enpass-linux.key | apt-key add -

Because of that we also have this error:

E: The repository 'https://apt.enpass.io stable InRelease' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
I'm trying this one fresh new installation (ubuntu 20.04). It should be pretty easy to verify the error with a new installation.
Please let me know if any more information is needed.
Edit:
I managed to fix my problem by deleting manuelschneid3r.asc.
sudo rm /etc/apt/trusted.gpg.d/home:manuelschneid3r.asc
