Please ask on the gnupg-users at gnupg.org mailing list for help. Note that you
do not need to subscribe but just a wait a bit until our moderators will approve
your mail. But anyway here is a quick hint in case you did not already tried:

$ gpg --card-edit
gpg/card> admin
gpg/card> factory-reset

This is an issue of GNOME as packaged by Red Hat. Please file a bug in Red
Hat's bug tracker instead.

I don't have sufficient permission to upgrade gnome session, so if you have
any idea suggest me

Use a recent gnome version and you are fine.

This seems to be a general question on how to use the software. Please read the
HOWTOS at gnupg.org and if you still have questions ask at the gnupg-users
mailing list.

scdaemon is part of GnuPG.
OpenSC is entirely unrelated to GnuPG.

Please take this to a mailing list (e.g. gnupg-users)

Ah sorry I understood you were saying the bug is in OpenSC. Where can I report
to scdaemon? I can't find it.

FireFox is not GnuPG and does not support the OpenPGP card.

As I said, the card may work with gpgsm because I once developed support for the
Belgian eID card. But it is likely to need some tweaking (gnupg/scd/app-p15.c)

I saw that it says not supported, but DNIe is actually supported. I can use it
flawlessly with Firefox for instance.

Thanks!

Please ask on the gnupg-users mailibng list for help.

With GnuPG 2.1 and a recent ssh versions you can keep the private key on the
local machine but use it on the remote machine for decrytpion or signing.
Checkout --extra-socket in the gpg-agent man page. This is not possible with 2.0.

I am sorry, but this is a bug tracker and not a help line.
Please ask on the gnupg-users mailing lists:

Please ask on the gnupg-users mailing list.

Please do not open another bug but comment on the very same bug you posted a few
days ago (issue2166).

In any case, this is a question and not appropriate for a bug tracker. Use one
