Here I can confirm I was able to access my Yubikey with GnuPG/scdaemon 2.1.17 in Debian stretch fine until the 2.1.18 upgrade. Then it started to completely fail with: [996]anarcat@curie:~$ LANG=C gpg --card-status gpg: selecting openpgp failed: No such device gpg: OpenPGP card not available: No such device ... which is slightly different from the bug report here. The workaround is the same though, just adding "disable-ccid" to .gnupg/scdaemon.conf fixes the problem. This seems like an important regression, however. If "disable-ccid" should absolutely be added by users, this should be noted in the NEWS.Debian file. Alternatively, this should "just work" regardless of whether it's enabled or not. Thanks! a. PS: the details of my yubikey setup can be found here: https://anarc.at/blog/2015-12-14-yubikey-howto/ It should be fairly standard, and I added a reference to this bug there. -- The survival of humans and other species on planet Earth in my view can only be guaranteed via a timely transition towards a stationary state, a world economy without growth. - Peter Custers
