Canonical is planning an ‘All Snap’ desktop next year. It will likely be available side-by-side with the traditional deb-based installation we’ve been used to since 2004.
If the “All Snap” or “immutable” platform is to be a success, Canonical needs to get a grip on the broken, uninstallable, insecure, and outdated snaps provided in the snap store.
As I mentioned, there’s around five thousand snaps in the store. Hundreds of them haven’t been touched in years. Some developers have just abandoned their packages.
I want to see this situation improve. In general, Canonical should incentivise the promotion of applications and dis-incentivise letting applications languish.
You can use KDE on Debian, it’s a checkbox in the installer or you can use a Calamares live iso with KDE.
