[snap] cups-control should be auto-connected

[Ads20000]

I installed a printer using the Printers application but LibreOffice can't see it, even after a reboot.

To solve this problem so that the snap works out-of-the-box, the cups-control interface should be auto-connected.

Does connecting the "cups-control" interface help?

    snap connect libreoffice:cups-control :cups-control

[Ads20000 (ads20000)]

Yes it does, I'll update the bug title and description :)

[Ads20000 (ads20000)]

Though instead of auto-connecting cups-control maybe we should wait for software centers to introduce interfaces to allow people to connect various interfaces when the app is installed - but that may take a while... I'm sure someone like Niemeyer would have an idea of what to do here!

Status changed to 'Confirmed' because the bug affects multiple users.

[Ads20000 (ads20000)]

I requested this on the snapcraft forum here: https://forum.snapcraft.io/t/request-autoconnection-of-cups-control-for-libreoffice/2517

It hasn't got enough votes to be auto-connected, it seems...

[Ads20000 (ads20000)]

cups-control is now auto-connected :) https://forum.snapcraft.io/t/request-autoconnection-of-cups-control-for-libreoffice/2517/19?u=ads20000
