Upstream has also made a change to have scp use the SFTP protocol by default. This will appear in OpenSSH 8.8. You can test SFTP protocol mode now by passing the -s flag to OpenSSH (in main/-CURRENT). Commit message: Author: djm@openbsd.org AuthorDate: Wed Sep 8 23:31:39 2021 +0000 Commit: Damien Miller CommitDate: Thu Sep 9 12:35:37 2021 +1000 upstream: Use the SFTP protocol by default. The original scp/rcp protocol remains available via the -O flag. Note that ~user/ prefixed paths in SFTP mode require a protocol extension that was first shipped in OpenSSH 8.7. ok deraadt, after baking in snaps for a while without incident
