[maemo-developers] how to change public keys in garage.org

[From: Olivier ROLAND]

Hi,

I was off for some times and unfortunatly I lost my keys.
I need to submit my new public GPG/PGP key and public SSH key to upload 
streamtuner packages to the repository's incoming queue but don't find 
how to do that from garage interface. Can you tell me how to renew 
public keys in garage ?

Thanks.

PS: i have already sent this request to garage at maemo.org 2 weeks ago and 
ferenc at maemo.org later but get no answer yet. Maybe lost in spam land ...
