OK, thanks!
I am looking at this now. From looking at this it is actually telling me to edit the lines and replace “stretch” with “buster”. Is that correct?
I ask because when I try to run the update via MyOSMC it says that it is “Downloading Update” then I get a message that “cache is updated” then it says that there are no updates available. I am interpreting that to mean I am as up to date as i can be with the current sources list. Is that accurate?
It looks like what I need to do is change the sources to “buster” so it actually can update?
