gnupg2 : pinentry cache is not clear : gpg-agent

[Michel Le Cocq]

I encounter the same bug as this Debian one : [Debian Bug report logs - #919856](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=919856).

I've test gpg-agent with gnupg2 and pinentry with this several version and all have the same trouble :

Ubuntu 18.04.2 LTS Bionic Beaver
gnupg2 2.2.4-1

Ubuntu 18.10 Cosmic Cuttlefish
gnupg2 2.2.8-3

Ubuntu 19.04 LTS Disco Dingo
gnupg2 2.2.12-1

In fact it's a GnuPG bug see : [https://dev.gnupg.org/T4348](https://dev.gnupg.org/T4348)

This bug is corrected in GnuPG 2.2.13-1.

Thank you for your bug report. Do you have steps that can be used to trigger the issue?

[Michel Le Cocq (nomad-fr)]

it's exactly the same procedure has describe in Debian bug.

In fact I configure a yubikey with a ssh key inside.

Whenever I try to connect somewhere, where I'm sure my pub key is I get:

 sign_and_send_pubkey: signing failed: agent refused operation

I just see the fix is committed, when will we see it ?

[Sebastien Bacher (seb128)]

It's commited upstream and in Debian so we will get it when next Ubuntu cycle start. Then we can look at doing a SRU but for that we need a testcase which can be used to verify the SRU (and ideally which doesn't require buying hardware like an yubikey)

when you say next cycle it's version 19.04 or something else ? like 19.10 ?
