It's complicated to have a good solution, because we need to change assumption (serial number identifies keys).

Hello again - can I ask about the status? Or should I consider this as a no-fix? Anything I can assist with?

As this update lists multiple issues and following fixes for them, maybe it was resolved by Microsoft?

But sadly I can't see any problem with the mail. Looking at the source of the mail it has the image as one attachment. That attachment is displayed. There are no other attachments part of the mail and so other clients also only show that one attachment.

I have sended the email...

Without more reports and without the info needed to analyze this further I'm lowering the priority.

Closing this as invalid until the info requested in the last comment is provided.

I've tested it with Gpg4win-3.1.7, too and it works for me so something must be special.

this error comes to me when I try to decrypt a message and I get this message

For what I use, please refer: https://tracker.debian.org/pkg/gcc-9

Which one version gcc 9 you've been using?
May I see gcc -v ?

@gniibe already wrote: “With gcc-9 in Debian experimental, everything goes well.”

BTW: fedora corp provides already free access to build envs with gcc 9 which can be easily integrated with CIs.

What you mean " it is not reproducible for u"?
Did you try to use gcc 9 and you had no problems compiling gnupg or you don't have access to build env with gcc 9?
Try to google to "gcc 9 pragma" and you will find several discussions and patches done by people fixing similar issues.

well, Firefox DE on OSX gives same error Unhandled Exception ("HTTPFutureHTTPResponseStatus")

Hi there,

I would have thought this is a logical usage for gpg cards - seems this is harder to achieve as I thought.

I think Bash 5.0 is in sid, not testing yet. Are you sure it's related to Bash 5.0? Is there any possibility your upgrading some other software causing this?

That's exactly the point: I do want one common encryption key between the two cards: So I can distinguish between the two, but en-/decrypt with both.
One is on the GnuPG SmartCard, the other on a YubiKey - output --card-status (some things xxx'ed out) :

Please show us your output of gpg --card-status for each card, and tell us the reason why you think "the pgp db seems screwed up".

For my test, six distinct keys (three subkeys for each smartcard) works fine.
IIUC, you try to use same decryption key by two smartcards. Currently, it is not supported.

Is it an issue when you share an decryption key E among two smartcards?
I think that when there are six distinct keys (three subkeys for one smartcard each), it works fine.
I'll try to make reproducible test case.

FWIW, the canonical way to make sure that gpg-agent has been started is to run

You're very welcome. In my instance, this is "resolved" - I now get the prompt I realised I needed so to me this bug could be considered closed or wontfix, but I'll leave you to do with it as you please.

Basically, you are right. In addition, gpg-agent asks scdaemon about list of card/token.

OK - so if an entry is not required in sshcontrol for a smart-card key - is the private key stub sufficiently detailed enough for the agent to realise that it can ask for that card to be inserted for an ssh connection?

sshcontrol entry is required for non-smartcard keys, but not for keys on smartcard. This is intentional. For gpg-agent and current format, it is only the information for gpg-agent to know if a key is for SSH or not.

Also - going back to sshcontrol - with an ssh key added to the agent with ssh-add, an entry in sshcontrol is required - but not for a key on a smartcard. Is that intentional, or just a byproduct of the smartcard diversion that happens?

Oh, wow - yes, adding to sshcontrol brings up the prompt - I do however need to stop the agent from being restarted on insertion for it to subsequently ask for the unlock.

I see your point. You are right. For SSH access, it just fails without asking insertion. It's not Windows specific.
I checked the change of history of gpg-agent, but I cannot find prompting insertion was supported.
So, I don't thin this is a regression.

Yes, it's running. I have a scheduled task that spawns a vbscript to ensure that gpg-agent is started on login, and restarts it on insertion of a card (specifically for two reasons: windows ssh clients don't typically start agents automatically, and windows can cause gpg-agent to get a but upset after a card is removed and re-inserted. Edit: although, I think that latter reason might be resolved now... I haven't investigated deeply. more info here and here).

Thanks for your information.
Hum, you are using gpg-agent for SSH access.

When no card is inserted, usage of an ssh client simply fails to request insertion of the card for the stub keys present in ~/.gnupg/.

It seems it's Ubuntu specific: https://bugs.launchpad.net/ubuntu/+source/imagemagick/+bug/1796563

Please let us know the version of GnuPG, the output of gpg --card-status when inserted, and how gpg is not working well, etc.

No info received.

I finally got around to look at your examples. Sorry for the delay. I can reproduce the issue and understand the problem.

updated example sent.

@dkg does --no-keyring solves the problem for you?
