Hi all,
Using (Fedora 31) a yubikey for both storing GPg-keys and ans SSL- certificate seems to create a conflict between pcscd and scdaemon.
Using gpg-agent is most usefull, it will avoid asking for the key/Yubikey password all the time; however: it will start scdaemon and both pcscd and scdaemon try to access the smartcard reader exclusively:
Depending on which is (re)started first:
Jan 28 12:01:25 laptop-winfried.blabla.bla pcscd[9786]: 00033944 winscard.c:286:SCardConnect() Error Reader Exclusive jan 28 12:01:25 laptop-winfried.blabla.bla pcscd[9786]: 00034140 winscard.c:286:SCardConnect() Error Reader Exclusive jan 28 12:01:25 laptop-winfried.blabla.bla pcscd[9786]: 00033895 winscard.c:286:SCardConnect() Error Reader Exclusive jan 28 12:01:25 laptop-winfried.blabla.bla pcscd[9786]: 00034205 winscard.c:286:SCardConnect() Error Reader Exclusive jan 28 12:01:25 laptop-winfried.blabla.bla pcscd[9786]: 00032693 winscard.c:286:SCardConnect() Error Reader Exclusive jan 28 12:01:25 laptop-winfried.blabla.bla pcscd[9786]: 00031293 winscard.c:286:SCardConnect() Error Reader Exclusive
Or when pcscd, gpg is not abaile to communicate with the card reader resulting in:
gpg2 --card-status gpg: selecting card failed: No such device gpg: OpenPGP card not available: No such device
Most topics "on the internet" mention to disable pcscd when using gpg or
in $HOME/.gnupg/scdaemon.conf using "disable-ccid" pcsc-driver /usr/lib64/libpcsclite.so.1 disable-ccid
The latter however just won't work; gpg will not be able to access the smartcard.
FYI; is seems it is not an "exclusive" Yubikey problem. Besides yubikey, I also use a gnuPG (OpenPGP) Smartcard. different card, different card reader same problem...
Hence: any solution for pcscd an scdaemon to work together....?
