Muon accesses api.opendesktop.org without informing the user

[Sergio Callegari]

Looks like at every invocation muon-updater accesses api.opendesktop.org.
This is done without a clear reason, since the updater should check the apt lists configured in ubuntu that don't include anything at opendesktop.org.
Furthermore, this is done without the user being informed about it, nor without the user having the possibility to disable this functionality.

Not a bug. It access opendesktop to update plasma widgets and whatnot.

Sorry, this is not mentioned in the package description anywhere and seems something the user should be informed about.

I was expecting the package to be a KDE replacement of synaptic and the other apt frontends available in ubuntu, not to update part of the system out of the deb packaging system or what the user controls via the apt lists.

Out of curiosity:
Where do the updated plasma widgets go in the system?
Does this mean that if I disable everything in the apt lists a kubuntu machine keeps updating part of the system?
Why is the whole functionality of muon-updater broken if I do not authorize it to contact opendesktop.org using the expired certificate dialog? (namely, updated deb packages cannot be installed)
Can it be that the fact that opendesktop needs to be contacted is the reason why in many occasions the following happens? A notification icon appears about security updates; one clicks and the muon updater opens; the list of the upgradable packages is shown for an instant then it disappears; the updater shows just a progress indicator; this can last for many minutes.
Is apper the same in this respect?

Thanks for any information you may provide
