Unable to locate package openssh

This error typically occurs when the package manager cannot find the requested package in its repositories. To resolve this issue, you can try the following steps:

1. Update the package lists:

   sudo apt update

2. Install the package:

   sudo apt install openssh-server

If the issue persists, it's possible that the package may not be available in your current repository. In such cases, you can try adding additional repositories or manually downloading and installing the package from a trusted source.

Please note that these instructions assume you are using a Debian-based Linux distribution like Ubuntu. If you are using a different distribution, the package manager and commands may vary.
