Comment 3 for bug 1719746

I have never used the gdebi/firefox method that is talked about but I do use gdebi to install packages that are available only manually such as plexmediaserver.

It can still be used by opening gdebi first from the "Activities" menu top left then using "File -> Open" menu item, but I can not find it after a right click on a .deb package ->Open with menu so there is no way to set it as the default application to open .deb packages.
