Dear Savannah Help Team,
I am trying to access the GNU Scientific Library (GSL) repository via SSH using
my Savannah account (malik_n), in order to mirror it onto our internal company
Git server.
I have registered my public SSH key on my Savannah account, but I am still
getting a “Permission denied (publickey)” error. I have verified that the key
I’m using matches the one registered on the key management page.
Below is the requested debug information.

Could you please check whether my SSH key is correctly associated with my
account, and whether my account has the appropriate permissions for accessing
the GSL repository via SSH?
Thank you very much for your assistance.
