I've run `snap install ghostwriter` on an Ubuntu 22.04 installation. It seems to have succeeded, but it also produced a cryptic warning in the process: $ snap install ghostwriter 2024-02-12T12:00:03+01:00 INFO cannot update "cups", will not have required content "foo": snap has no updates available ghostwriter 23.08.4 from KDEβ installed Regardless of whether the warning should have been shown at all, the "foo" part got me confused. It seems to come from <https://invent.kde.org/packaging/snapcraft-kde-applications/-/blob/7c80c0c285153f5951c028c164279bd65e591bc2/ghostwriter/snapcraft.yaml#L49>; using a more descriptive name than "foo" would be helpful.
It was for auto install of cups as suggested by documentation. Though I have removed it as it silently broke other things. One must snap install cups manually now.
