|
|
I've recently bought a YubiKey4, and while getting the FIDO U2P and OATH-SHA1 to work
wasn't trivial (some udev hacking needed), it now works well.
However, I'd also like to use the OpenPGP SmartCard feature, while running
'gpg --card-status' as root, outputs info about the Key, running it as my regular user just
gets me "gpg: OpenPGP card not available: Not supported".
/var/log/messages on card insertion:

My user is a member of the group plugdev.
Any help in getting this to work is appreciated.
Edit: Made an error with the paths, they are udev rules, nothing to do with pam.

Have you tried newgrp or restarting your session? |

Yes, I did. In fact, just to make sure, I've even rebooted my machine. |

Is there some way that I can check which device gpg is trying to use?
To me this seems to be a problem with access rights, since I can easily access the card as root.
I assume that some more udev hacking is needed. |

Normaly you don't need to change udev rules changes for the yubikeys.
Are you in the "pcscd" group? |

@py-ro: Thanks for the suggestion, I was not. I am now, unfortunately this didn't change anything.
Code: |
➜ ~ % su - fklama
Testing for gpg-agent
No Agent, starting...
GPG_AGENT_INFO=/tmp/gpg-KLchJU/S.gpg-agent:31531:1; export GPG_AGENT_INFO;
SSH_AUTH_SOCK=/tmp/gpg-D2CGeF/S.gpg-agent.ssh; export SSH_AUTH_SOCK;
SSH_AGENT_PID=31531; export SSH_AGENT_PID;
➜ ~ % groups

➜ ~ % gpg --card-status

If you accessed the "card" as root, you need to replug it atleast. Also make a new user Session, su alone won't work well for "reasons". |

@py-ro: I always replug my key whenever I try this. I've just tried a fresh login and still no luck.
I've just tried it on a Debian machine, as the user, it works there, without any problems.
This is really frustrating. I like Gentoo, and a recent problem I had with GFX drivers just stopping
to work with Debian has just shown me why I use Gentoo. But I wish these things would just work. |

Solved it, I ran gpg --card-edit as root and found the device it was using,
and found that I need to add my user to the usb group. Now it works.
It also seems I need to issue a:
Code: |
gpg-connect-agent RELOADAGENT /bye
|
after reconnecting my YubiKey, or gpg won't recognize it again. |
