Change:
yubioath-desktop is unable to talk to YubiKey devices, seemingly because it is unable to import the python module. Steps to reproduce the behavior: from a terminal No Python errors, and the TOTP tokens to show up in the UI. This is what the UI displays, indefinitely. ! The behaviour is the same regardless of whether a YubiKey device is present. is installed via , using a flake-based config.
It's not clear to me, which python package they want here.
It looks like upstream has deprecated this package in favor of:

Hi! The error is caused by a dependency on yubikey-manager5, while yubioath-desktop still needs yubikey-manager4, because the python libs had breaking changes (see ). By dropping the dependency to , this can be fixed. A workaround: A suggested fix: Change and I know that this package is dropped in master () but this could be a relatively simple fix for 22.11, before changing to the new flutter-based gui. Thanks!
Thanks for the suggested fix, Submitted a PR: it gets picked up.
