Deployment fails beucase of SCP-Error
While deploying an error is thrown. Seems like a problem with SshNet?

I couldn't reproduce the error. Does the error always occur? What if the Project is opened from another folder? Is there write permission to the folder for the SSH user?
I found the problem and a workaround.
It seems the the SSH(SCP?) Server in my linux has fixed a security related bug. This leads to a problem with the SSH.NET library related issue
I compiled and included the 2016.0.0 version of SSH.NET into VSMonoDebugger and now I can debug on my embedded linux.
Thanks for troubleshooting. Unfortunately I had to upgrade to SSH.NET 2016.1.0.0, to avoid crashes with compressed content > 100 MB.
So I can't just downgrade. I must hope that the bug will be fixed in SSH.NET. Otherwise I would have to try to solve the error in a fork myself. But I just don't have the time.
Try to use the new extension VSMonoDebugger2022 with Visual Studio 2022. There I'm using the nuget SSH.NET.Fork.
