At present, the gtk-common-themes snap declaration has
slots-per-splug: * set for its
gtk-3-themes slots. Please update the
sound-themes declarations to also set
I had previously requested greedy plugging for the GTK theme slots here:
… and the same rationale applies to the other two slots: they are all designed to co-exist with other theme snaps.
As things stand, auto-connection of the two remaining slots can break if another snap providing the slot is installed (e.g. the
icon-theme-yaru-mate snap). As we’ve now got a daemon set up to prompt users to install missing theme snaps, it’s quite possible for non-technical users to get their system into this state.
