After updating to dev-python/pyscard-2.2.2 it is no longer possible to run app-crypt/yubikey-manager (running 5.6.1 specifically here. I suspect 5.5.1 is just as affected though). All crypt/yubikey-manager ebuilds should be depend on <dev-python/pyscard-2.2.2. Downgrading to dev-python/pyscard-2.2.1 resolves the issue Reproducible: Always Steps to Reproduce: 1. emerge -1 '=dev-python/pyscard-2.2.2' 2. ykman Actual Results: Traceback (most recent call last): File "/usr/lib/python-exec/python3.12/ykman", line 5, in <module> from ykman._cli.__main__ import main File "/usr/lib/python3.12/site-packages/ykman/_cli/__main__.py", line 42, in <module> from ..pcsc import list_devices as list_ccid, list_readers File "/usr/lib/python3.12/site-packages/ykman/pcsc/__init__.py", line 37, in <module> from smartcard.pcsc.PCSCContext import PCSCContext ModuleNotFoundError: No module named 'smartcard.pcsc.PCSCContext' Expected Results: ykman can successfully run.
