What, exactly, is the issue here? There's at least three different things mentioned here and two of them are correct behaviour.
E: Unable to locate package winehq-staging
That could be an issue, or you could have just hit the repo while it was getting updated, though I can't image that takes more than few seconds. In which case you could just try again.
It works fine here. I assume it's now working fine for you?
If wget is incorrectly reporting that a file has not been updated, when it doesn't exist, then this has nothing to do with Wine and should be fixed in wget. However, I doubt that is the case.
The suspicion is that the local file was modified or the contents when it was download differ from the current ones, yet wget refuses to download the new one. So one test was to "cat /etc/apt/sources.list.d/winehq-lunar.sources" and see what's really inside. But since was removed now we can't know if its contents match the ones currently in the server or not.
