Steps to Reproduce:
I am opening this issue because issue #7426 won't allow me to comment and the solution in that thread is not working. When I run the sudo command I receive no matches found.
I figured it out.
For anyone else who finds this and had a similar issue, the solution in https://github.com/sparkle-project/Sparkle/issues/936 worked for me
solved by CMD+dragging (so that it moves the app instead of making a shortcut) the app back to the downloads folder and then dragging it back to the applications folder.
