This breaks SSH2 uploads on modern systems where this public key signature algorithm is [https://www.openssh.com/txt/release-8.2 disabled by default]. (This problem currently affects Fedora 33.) Changing it to a supported algorithm makes it work again. (I used 'ssh-ed25519'.) I wonder if we need to set the algorithm at all? Can't we let SSH just negotiate one from it's set of supported algorithms?",defect (bug),closed,normal,5.9.3,Filesystem API,,normal,fixed,fixed-major,,
