> Any chance that your upgraded ssh doesn't accept your key? I think you could generate a new key, register it on Savannah, and try cloning with it.


Just figured the fix, from links below, by adding:

PubkeyAcceptedKeyTypes +ssh-rsa

Searching in Google for some keywords, first hit was https://confluence.atlassian.com/bitbucketserverkb/ssh-rsa-key-rejected-with-message-no-mutual-signature-algorithm-1026057701.html that points to announce of ssh-rsa being deprecated in a future release as seen in https://www.openssh.com/txt/release-8.2

Right now I am using openssh-8.4p1 and it is now required to regenerate keys or use the option.

  I did not push a commit for one year to GNU Lightning, but
I did not just silently give up on maintaining it. For the moment
I have been supporting either on mailing list or off list some
users that have it embedded on their software, and frequently
updating from latest git.
  When working on merging some patches from a contributor, I
noticed I could no longer git update or git checkout.

-email is unavailable- should be an alias to -email is unavailable-

"""

  I do not need shell access, just ssh debug below:
