Solutions you've tried

Change Subsystem sftp /usr/libexec/sftp-server to Subsystem sftp internal-sftp in /etc/ssh/sshd_config.
After that scp works.

-O flag for scp is needed when copying to dts for some reason.

[m-iwanicki]

It might be because there is no sftp-server installed, there is no file at /usr/libexec/sftp-server.
So we can either add sftp-server or change sshd_config to use internal-sftp
