Hello,
I use Manjaro Linux and am trying to update the firmware on my Nitrokeys 3A NFC. I have Nitrokey App 2.3.0 installed (from flatpak). The app recognizes my Nitrokey and shows its firmware version as v1.6.0, variant LPC55, init status ok.
Check for update shows that firmware v1.7.0 is available. Pressing ok, I get a request to touch the nitrokey. Nothing happens though after I touch the NK. The update process seemingly times out after a few seconds and I get Nitrokey 3 updated failed. No actual download of the new firmware or installation attempt appears to happen (the progress bar never goes above 0%).
