Hi there,

after upgrading to 2.1.18-7 my yubikey stops working again.
In difference to #852702 I can't get serious output to append to the bug
report since an "gpg --card-status" dont' get me any update.

After a downgrade to 2.1.18-6 all works again like a charm.

Related packages are: dirmngr, gnupg, gnupg2, gnupg-agent, gnupg-l10n, gpgv, scdaemon

If you need additional information or anything that I can troubleshoot,
tell it :)

Shin
