SSH SFTP Updater : “Private key incorrect for user”

If you’re using WordPress SSH SFTP Updater plugin, and you got the error “Private Key is Incorrect for use”… even when the keys are correct, check the following:

[cc lang=”bash”]nano /etc/ssh/sshd_config[/cc]

If there is a “ForceCommand internal-sftp” directive, somewhere, in sshd’s config, try disabling it. That was what was causing me issues:

I had an sftp-only user, and the WP plugin doesn’t support that!.
