Thanks for your detailed explanation, that will definitely come in handy often!

Virt-manager has a .deb download on the website, so I assume that means they distribute a .deb release. What needs to happen to have their up-to-date .deb uploaded to Shop?

My preffered method is using the Shop as I like the convenient, and what I’m just unsure of is how the Linux Appstores function. Does the app developer have to upload their latest update to the shop? Or do the PopOS devs need to add it themselves? Is there anything the community can do to help?
