Description Nate Graham 2017-12-22 16:13:56 UTC
I use Discover on Kubuntu 17.10 with the following PPAs installed:
- Kubuntu backports (provides newer versions of KDE software)
- VLC nightly builds (provides a newer version of VLC)

These PPAs provide versions of their software that have AppStream IDs identical to the versions provided by the regular Kubuntu 17.10 repos.

I know that Discover has a backend switcher UI: https://www.youtube.com/watch?v=qzOZZvabNeg&spfreload=10

However, Discover doesn't show the backend switcher on the Application Pages of any apps that are available from both a PPA and the distro packaging. Instead, the PPA version is always shown and the distro-provided version is unavailable until you manually disable the PPA.

I'd say PPAs are deprecated. I prefer spending time in other stuff.

Okay, fair enough.
