Somme applications are not on the flathub

the-entropyst · November 5, 2025, 3:03pm

As I tested KDE Linux alpha, i found ood that not all KDE applications are available OOTB in discover. There is 2 solutions : add the snap support or port missing apps on flathub.

At this time the following applications are not available as a flatpak :

Merkuro
KMail
Konqueror
KOrganizer

It is all I found and there might be others.
Nothing urgent but it would be nice to fix it before KDE Linux get stable.

KMail, KOrganizer, and Merkuro are all in https://flathub.org/en/apps/org.kde.kontact (all together because they all use the same Akonadi instance, I believe)

Doesn’t KDE Linux already have Snap support?

That makes sense, otherwise you’d need to duplicate the account information, caching, etc.

I guess Flatpak currently doesn’t support service flatpaks which other apps could depend on.

KDE Linux should probably run Akonadi on the host and export it to Flatpak apps, otherwise it will be difficult for things like the digital clock applet’s calendar integration.

KMail and KOrganizer are part of Kontact indeed. Merkuro however is a independent application suit made with Kirigami (Kontact use QtWidget). Merkuro also use Akonadi

Snap is packed into KDE Linux but it’s not integrated within Discover (yet?). I’m also thinkg for other atomic distros like Fedora Kinoit that rely only on Flatpak

So only Merkuro and Konqueror are missing from the Flathub
(and maybe other apps that i did’t mentioned)

lack of digital clock PIM integration would be a deal breaker for me.

Merkuro is in the manifest, but I don’t have it installed to check

Never found any trace of Merkuro as a user (in the Flatpak at least)

It’s there, you can run flatpak run --command=merkuro-calendar org.kde.kontact, but the flatpak finish-args needs to be updated, I get

kf.dbusaddons: Failed to register name 'org.kde.merkuro.calendar' with DBUS - does this process have permission to use the name, and do no other processes own it already?

and it quits. It seems like no one uses it in the flatpak.

AFAIK Merkuro is intended to use Akonadi but to be independent from The Kontact suit. Merkuro aim mobile devices which is not a goal for Kontact. This is why I believe that they should both be available on Flathub as seperate application.

I easely see a Akregator/Alligator relationship between. They both fulfill the same usecase but one is desktop only and the other is mobile friendly

The Merkuro case look like a bit tricky. But Konqueror is still missing :
