Message:

Filesystem API: Include the ssh-ed25519 public key signature algorithm as an alternative to ssh-rsa.

The ssh-rsa signature algorithm is disabled by default as of OpenSSH 8.8, which breaks SSH2 uploads in WordPress on modern systems. ssh-ed25519 is one of the suggested alternatives, supported since OpenSSH 6.5.

References:

Follow-up to [8865].

Props richybkreckel, dd32.
Fixes #52409.
