unable to authenticate with public key

Asked by Emmanuel Lambert on 2009-08-24

The PUSH command is not working because BZR doesn't seem to be able to do the SSH authentication.

I keep getting the "Permission denied (public key)" error :

emmanuel@emmanuel-ubuntu:~/Software/Download/meep_install/python-meep-launchpad/devel$ bzr launchpad-login elambert
emmanuel@emmanuel-ubuntu:~/Software/Download/meep_install/python-meep-launchpad/devel$ bzr push lp:~nizamov-shawkat/python-meep/devel
Permission denied (publickey).
bzr: ERROR: Connection closed: Unexpected end of message. Please check connectivity and permissions, and report a bug if problems persist.

Also, simple SSH doesn't work :

emmanuel@emmanuel-ubuntu:~/Software/Download/meep_install/python-meep-launchpad/devel$ ssh -v <email address hidden>

I re-generated the public keys a dozen of times, both RSA and DSA (and re-uploaded to launchpad), none seem to work.
I've set the persmissions on the .SSH files :

emmanuel@emmanuel-ubuntu:~/Software/Download/meep_install/python-meep-launchpad/devel$ ls -l /home/emmanuel/.ssh
total 12
-rw------- 1 emmanuel emmanuel 1671 2009-08-24 10:11 id_rsa

-rw-r--r-- 1 emmanuel emmanuel 540 2009-08-24 10:12 known_hosts

How can I find out what is wrong?

I would appreciate if anyone could help me with this. I've been struggling with it for 2 days now and to no avail. Anyone a suggestion? Thanks a lot.

Emmanuel Lambert (emmanuel-lambert) said : #2

ok, I found the solution.
It turns out that Launchpad expects the PPA username, not the original username that is still displayed as username !!!

Xabi (xabii) said : #3

And how did you do that? can you tell me please?

Vincent Ladeuil (vila) said : #4

@Xabi: Do what ?

Inform bzr to use a username ? 'bzr launchpad-login --help'

Find which username launchpad associate to your displayed name ? Look at the urls related to your overview page or edit your personal details, both the name and the display name are displayed there.

I tried all above to no avail. I checked the username and to no avail. Is there are way remove login details and maybe re-enter them?

Koketso Mabuse (koketso) said : #6

Ok I managed to see my fault and fixed it, I reinstalled my system but on the previous system install I had use a different name for my PC so what i had to do was to recreate a new key and replace username and the RSA key as well.

Ta! Folks.
