Yubico Forum

I have two yubikeys and I am trying to reproduce the process to replace one key in case I loose it.
Basically I use yubikey for OTP and GPG(ssh and sign code/commits/branches...), I imported the same set of keys to both yuikeys, when I try to use the second yubikey to do the same tasks I face this issue: "Please remove the current card and insert the one with serial number:
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
Hit return when ready or enter 'c' to cancel:"
ssh and git seems to be keeping references to the old key hardware, serial, and it is not accepting the new one. I found a workaround for the ssh issue in this url: http://donncha.is/2014/07/problems-using-an-openpgp-smartcard-for-ssh-with-gpg-agent/
But was not able to find a workaround for the git issue.
I really appreciate any help.

Thanks,

A bit of an old thread, but I had the same problem. I found it was because my secret keys were also stored in my gpgkeyring (had been messing around with PIV). To fix

Delete secret keys from keyring

Verify keys are gone

Re-add secret key stubs

Restart gpg-agent for good measure
