It is illegal for different package names to contain the same desktop files. For example: virtualbox-5.1: /usr/share/applications/virtualbox.desktop virtualbox-5.2: /usr/share/applications/virtualbox.desktop virtualbox-6.0: /usr/share/applications/virtualbox.desktop virtualbox-qt: /usr/share/applications/virtualbox.desktop The solution would be to rename the common files that are also contained in Ubuntu's repos: virtualbox-5.1: /usr/share/applications/virtualbox-oracle.desktop virtualbox-5.2: /usr/share/applications/virtualbox-oracle.desktop virtualbox-6.0: /usr/share/applications/virtualbox-oracle.desktop virtualbox-qt: /usr/share/applications/virtualbox.desktop Notice the ""virutalbox-qt"" package is from Ubuntu repository and can therefore not be changed. The message below is from the syslog and it is caused by the conflicting virtualbox.desktop files from Ubuntu's repos and Oracle's repos. Gnome package manager detects that /usr/share/applications/virtualbox.desktop is from Ubuntu's virtualbox-qt package, but that desktop file is being provided by Oracle's virtualbox-6.0 package. So, gnome-software thinks there is an installation problem with the packages because of the installed files that belong to both package names.
