Hi John, Is the subject line of your question correct? Ubuntu 10.04? If that is not a typo, that could be contributing to your problem. I believe that the current stable release of Ubuntu is 18.04. According to the following link ubuntu 10.04 was released almost 10 years ago and was "retired" about 5 years ago.
