Re: Problems with Ubuntu 15.10 on one machine, but not anoth

I finally nailed! What I did was using pcsc_scan, and took the name of the reader from there to the "reader-port" configuration of scdaemon.conf. By taken the whole string it worked. When adding another reader-port entry for my Neo4 I could see that one as well using gpg2 --card-status

Now I have another problem, but this seems unrelated, so I'll create a new thread for this. But my Neo3 can decrypt mails at least, nice!

I made the update of the scdaemon.conf file, did a "killall scdaemon" and "killall gpg-agent" just in case, but none of the killall found any process so it was apparently not needed. I also took out the Yubikey and reinserted it again.

Anyway, here's my terminal session:

$ gpg2 --card-status
gpg: can't connect to the agent - trying fall back
scdaemon[25686]: enabled debug flags: command mpi crypto memory cache memstat hashing assuan cardio
gpg: selecting openpgp failed: Card not present
gpg: OpenPGP card not available: Card not present

This is the scdaemon.log (two attempts with card status):

Might it be some library that is too old to handle Yubikey?

I also tried starting a virtual machine and doing a fresh install of Ubuntu 15.10 adding Yubico ppa to it. gpg2 can see the yubikey, but I couldn't use it anyway (hardware error or something). Might be an error due to being a virtual machine, or perhaps is a clue to the real issue. Not sure which. Worth nothing however that in the VM I'm trying the Neo4, above is using Neo3. And I'm also trying key-signing using the Neo4 and VM, while I'm trying decryption using Neo3 on the host. Not sure if that makes any difference, though...

Just to be clear, does this still work on your offline computer?

I believe gpg is trying to use your other card reader.

Try to disable it and restart scdaemon+gpg-agent or add "reader-port Yubico" to ~/.gnupg/scdaemon.conf (if you do this also add "log-file /tmp/scdaemon.log" and "debug-level guru" to get debug info from scd).

Problems with Ubuntu 15.10 on one machine, but not another

2016-02-01T21:01:19+01:00

Hi,

I have an air-gap computer using Ubuntu 15.10, and I have downloaded my master key to my yubikey using it. I did not need to change any parameters for the yubikey to get gpg2 access to it, which I think I needed to do with my older yubikey.

However, now I try to use the key on my ordinary laptop, also using Ubuntu 15.10, but gpg2 cannot access it. Some details below:

dmesg:

I have tried killing scdaemon and gpg-agent, no difference in behavior. Something is different between these that happens to be significant, but can't figure out what.

Any suggestions as how to debug this?
