Started to work after further retesting. Perhaps some issue with Udev rules files?

[alex-nitrokey]

Let me know, if I can retest something.

[szszszsz]

Could you check please latest snap package, 21?
It works for me on Ubuntu 18.04.

[alex-nitrokey]

I only get it working with sudo rights on my VM on which no modifications were made.

[szszszsz]

I see. How have you installed/updated it?

[alex-nitrokey]

sudo snap install nitrokey-app --devmode
When installing it states that it is downloading (21) - which should be the version number, right?

[szszszsz]

Yes, 21 is the current version.
So to confirm, even with the --devmode switch it is not working for you? In that case Udev rules might be indeed the culprit. Would installing scdaemon help?

[alex-nitrokey]

I did try and funnily it didn't solved the problem either 🤔 But as far as I can see it didn't add the udev rules anyway.
But, after installing nitrokey-app via apt and removing it again (apt did not remove the deps), the snap is working fine. That means, any of the deps for nitrokey-app seem to be not included in the snap. Could this be the case?

[alex-nitrokey]

Okay, my fault. After installing scdaemon it helps to unplug and plugin again the Nitrokey 😉 sorry.

So yes, installing scdaemon does the trick, so probably something about udev rules? They are in the snap folder though...

This one is not occurring lately. More for completeness:

1. Current installation switch is --classic AFAIR.
2. The udev rules are included inside the package, however they are not available to system udev service. We would need to copy it outside of the isolated snap space to make it work automatically. We could think about this one in the future.

Closing as done.
