   My thanks to Lars (and any other developers) for obnam, I find it quite useful.
   
   I have been taking encrypted backups of my laptop onto a server using
   obnam. The laptop hard disk has now died. So now, even though I have
   the public/private key used for backup, I'm having a problem restoring
   the encrypted backup.
   
   I'm trying to locally mount the encrypted repo (using obnam mount) in
   an account on the server. The account login name is the same as the
   account on laptop used to create the backup. In this account on server
   I have transferred public/private keys from laptop account (which I
   luckily could before the disk conked out completely). I have even
   renamed the server hostname to be the same as laptop hostname. I
   believe I have also correctly configured gpg-agent.
   
   Now when I run 'obnam mount' (with appropriate config file and other
   arguments) via the gpg-agent the passphrase prompt is displayed. If I
   enter the correct passphrase, I get the following error:
   ERROR: R0C79EX: gpg failed with exit code 2:
   gpg: decryption failed: No secret key
   
   That I'm entering the correct passphrase is confirmed by the fact that
   If I enter a wrong passpharse, the "*** Bad Passphrase (try 2 of 3)
   ***" message is displayed, and the passphrase prompt is displayed
   again.
   
   I have verified that both public and private keys are available by
   using the backup key to encrypt and then decrypt a text file.
   
   In conclusion, my query is, why the error message (from gpg? or
   obnam?) even when the passphrase is correct and how to resolve it?
   Also is there any alternate method to restore an encrypted backup onto
   to a machine other than the one which was backed up?
   
   Regards

   The error message comes from gpg, not obnam. I have no idea what
   causes  it for you, I'm afraid. Are you sure the private is listed if
   you fun "gpg -K" (not gpg2)?

   Set --client-name to the name of the other machine, and make the
   private key available, and it should work.
