Package: chromium Version: 56.0.2924.76-5 The .desktop file in the chromium deb is not valid according to the desktop-file-validate tool.
The error is pretty self-explaining, it's referencing "chromium.png" for the Icon, it shouldn't do that (but only "chromium"): /usr/share/applications/chromium.desktop: error: (will be fatal in the future): value "chromium.png" for key "Icon" in group "Desktop Entry" is an icon name with an extension, but there should be no extension as described in the Icon Theme Specification if the value is not an absolute path
