That listed my older kernel packages! It listed all but the most recent one. You can also right-click on an entry and select "unmark," in case you wish to keep one or more listed packages to remove.

that is the corect place in Muon Package Manager to do the "Autoremove" option .

However it dose a "remove" NOT purge ,,,,,,,to get the "Purge" ,,,,,,,,you must .
go ,,,,Muon Package Manager>edit> Remove unnecessary packages>click one of the packages in the list>Ctrl+a to Highlight all packages>right click one and select "Purge">click Apply changes ,,,,,,,,,,,,,I just tested it in 16.04 and was left with the 2 newest kernels and "ect"
