Re: GPA finds YK4 but gpg --card-status throws error

Not, yet. And I cannot seem to find out why :/

Do you have any idea i could try?

Update:

Found the solution: Configure the GPG-Agent to start with --enable-putty-support and then run

Code:

eval $(ssh-pageant -r -a "/tmp/.ssh-pageant-$USERNAME")

from the git-bash and everything works!

Did you have any luck with git-bash ssh?

Okay, I got it (partially) working!

Solution was rather simple after digging into GPG-Configs on linux:

Set environment variables:
GNUPGHOME=%APPDATA%\gnupg

and use gpg2. That's it. Because if that variable is not set it will look in the wrong folder.
Need to start GPA once and then it's all okay

Still need to get git-bash's ssh working though, so I leave this thread open a little longer

[solved] GPA finds YK4 but gpg --card-status throws error

2016-06-19T15:46:37+01:00

Hi,

I just bought my 3rd Yubikey, the YK4, (neo and standard before that) and set it up on my Arch Linux machine. All no problemo, Now here's my problem:

When I use the GPA to access my YK4 on Windows 10 (dev machine, need git signing, hence cli tools) it all works flawless (get shown all details and can edit them), however `gpg --card-status --verbose` gives me this output:

Quote:

gpg: detected reader `Yubico Yubikey 4 OTP+U2F+CCID 0'
gpg: reader slot 0: not connected

gpg: selecting openpgp failed: invalid argument
gpg: OpenPGP card not available: general error

GPA:

Using the same yk and the same command on Arch works perfect.

I have already tried removing all drivers fro the device manager and installing newer USB drivers. Anything I missed in the setup guide? I am really at the end of my ideas and googleing the error also did not result in any solutions.

Update: Just tried this, without success, but a different error:
