This is just an FYI. I could not for the life of me get openssh to upgrade beyond 1:8.9p1-3ubuntu0.6

Would say of course verify your repositories before taking steps below. Take necessary snapshots: /etc/apt/sources.list.d/microsoft-prod.list

dpkg -l | grep openssh
(View your version)

Server:
wget http://archive.ubuntu.com/ubuntu/pool/main/o/openssh/openssh-server_8.9p1-3ubuntu0.10_amd64.deb

Client:
wget http://archive.ubuntu.com/ubuntu/pool/main/o/openssh/openssh-client_8.9p1-3ubuntu0.10_amd64.deb

SFTP:
wget http://archive.ubuntu.com/ubuntu/pool/main/o/openssh/openssh-sftp-server_8.9p1-3ubuntu0.10_amd64.deb

To Install is just: sudo dpkg -i [package]_8.9p1-3ubuntu0.10_amd64.deb

Example: sudo dpkg -i openssh-server_8.9p1-3ubuntu0.10_amd64.deb

Confirm after with:
dpkg -l | grep openssh
