An attempt at a routine git fetch (on the machine I have used for > 2 years…) fails :

charpent@zen-book-flip:/usr/local/sage-9$ git fetch
g...@git.sagemath.org: Permission denied (publickey).
fatal: Impossible de lire le dépôt distant.

Veuillez vérifier que vous avez les droits d'accès
et que le dépôt existe.

The same problem exists on g...@trac.sagemath.org:sage.git

Is there anything amiss on these repositories ?

Works for me. If it persists,
try generating a fresh keypair and upload the public key to trac.
Old RSA / DSA keys get rejected by newer versions of sshd.

A id_ed25519 key type appears to be a good choice.

That was it : generating and installing a ED_25519 key gave me access back.

Thank you Dima !
