The defaults.list handling is still valid, https://gitlab.gnome.org/GNOME/glib/-/blob/main/gio/gdesktopappinfo.c#L985
The issue is that it ranks lower than gnome-mimeapps.list which got install by error since a gnome-session merge this cycle http://launchpadlibrarian.net/569661464/gnome-session_40.1.1-1ubuntu1_40.1.1-3ubuntu1.diff.gz the >- don't install gnome-mimeapps.list (installed by desktop-file-utils in Ubuntu) was undone there +debian/gnome-mimeapps.list usr/share/applications/ or that list isn't customized by Ubuntu and taking over our defaults ** Package changed: desktop-file-utils (Ubuntu) => gnome-session (Ubuntu) ** Changed in: gnome-session (Ubuntu Jammy) Assignee: (unassigned) => Jeremy Bicha (jbicha) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to desktop-file-utils in Ubuntu. https://bugs.launchpad.net/bugs/1970248 Title: .deb files open with Archive Manager by default Status in snap-store-desktop: Triaged Status in gnome-session package in Ubuntu: Triaged Status in gnome-session source package in Jammy: Triaged Status in desktop-file-utils package in Baltix: New Bug description: Impact ------ Someone who downloads a .deb file usually wants to install the .deb when they open it. Opening it with Archive Manager is really confusing. Test Case --------- Download a .deb Open your Downloads folder with the file manager. Double click on the .deb The Ubuntu Software app should open with a button that says Install. More Details ------------ desktop-file-utils provides /etc/gnome/defaults.list In that file, there is this line (and several other lines also referring to the same .desktop) application/vnd.debian.binary-package=snap-store_ubuntu-software- local-file.desktop But when I look at /snap/snap-store/575/usr/share/applications/ there is gnome-software-local-file.desktop which is a different file name. I believe this issue can be fixed in either snap-store or with desktop-file-utils.
