Thank you for your prompt response. I was able to upgrade UNRAID OS per your instructions using the same usb drive.
The dockers and plugins installed continue to function, but I am not able to upgrade anything.
I removed the binhex-Krusader docker, as a test, and tried to add the docker again, but was not found locally.
Ran FIX COMMON PROBLEMS and got the following error message, but don't understand what is the solution.
Sorry, did not mean to hijack topic. Should I post elsewhere!?
