Source for deb apps in dropdown menu is empty

[AsciiWolf]

The source for deb apps displayed in the dropdown menu in window header on app details page is empty. See the attached screenshot. This dropdown menu is displayed only when there are multiple sources (debs or debs and snaps) available.

Also, with snap app that has also a deb source available, clicking the empty source correctly switches the opened details page from a default snap to the deb one, however the whole dropdown menu disappears from the window header.

Steps to Reproduce:
1. Open Snap Store and search for "SuperTuxKart"
2. Click the result to open its details page.
3. Open the dropdown menu in the window header.

The same issue also happens for apps that are available only as debs, but have multiple deb sources, see comment #2 for a deb-only example.

Also note that the URL and Format entries are missing as well, however when switching to the empty (deb) source and scrolling the page, its source URL is correctly displayed at the details section of the page.

Hmm, it seems that this issue also happens for apps that are available only as debs, but have multiple sources (multiple desktop files being a part of the application). For example the fldigi amateur radio app.

It seems that these AVCs are printed in journal when clicking the dropdown Sources menu on a details page of deb app that has multiple sources available (multiple debs or debs + snaps):

I hoped that the fix for missing icons (#1864307) could maybe also fix this issue. Unfortunately, the sources are still empty when using latest snap-store and ubuntu-desktop from focal-proposed.

[AsciiWolf (asciiwolf)]

The missing "Ubuntu" source name could indicate a problem with gsettings-desktop-schemas, at least in my opinion (but I am not sure), but can also be intended (I don't know Snap Store code changes that much).

By the way, note that the URL and Format entries are also missing, however when switching to the empty (deb) source and scrolling the page, its source URL is correctly displayed at the details section of the page.

[AsciiWolf (asciiwolf)]

Maybe it could be possible to somehow hardcode the origin name (for example see how this is handled for Flathub in upstream lib/gs-app.c). The repo name is correctly displayed on app details page, as I noted above, so it gets detected, but is not displayed in the dropdown menu for some reason.

Please let me know if there is anything else I could do (test, debug, provide additional info etc.) to help getting this annoying bug fixed. Some regular users that I recommended Ubuntu 20.04 to were already asking me how to install non-Snap apps because they did not realize that the empty space in Channel menu is actually another source that is clickable.

[AsciiWolf (asciiwolf)]

I have spend some time trying to debug this issue, but was unfortunately not able to find anything related to this issue in snap-store verbose logs or system journal.

[Mantas Kriaučiūnas (mantas)]

Maybe quick workaround would be to use original gnome-software from deb package instead of snap store?
snap remove snap-store && sudo apt install gnome-software

[AsciiWolf (asciiwolf)]

Still the same issue with latest stable snap-store 3.36.0-80-g208fd61.

[corrado venturini (corradoventu)]

Still with snap-store 3.36.0-82-g80486d0 481
has the maintenance of snap-store been abandoned?

Yes, Emacs is an example of this, I've attached an screenshot showing it.

[Sebastien Bacher (seb128)]

That's still an issue with the 3.38 snap-store version in edge, the gnome-software from the archive works fine (though it lists entries as 'Ubuntu' without any visible difference). The selector seems to show on deb with several candidate versions (for example those having a SRU available)

[Mateusz Stachowski (stachowski-mateusz)]

I confirm that the newest snap-store in 20.04 LTS works as expected and displays entries in the dropdown menu.

I've checked SuperTuxKart, GIMP, fldigi, Emacs and Krita.

snap-store 3.38.0-59-g494f078 (518)

[Jeremie Tamburini (jeremie2)]

Just tried the updated snap-store version 3.38.0-59-g494f078 and most of the apps show both version (snap/deb) in the drop down menu. Thank you very much for the improvement!

But... for some applications like Firefox and Thunderbird still doesn't work.
For instance, searching for Firefox we'll get two different results:
- "Firefox Browser Web" for debs. (Dropdown menu shows only deb packages)
- "Firefox" for snaps. (Dropdown menu shows only snap packages)

[Sebastien Bacher (seb128)]

The firefox case is a another problem and due to bug #1871723
