To make fonts auto-install work coverage auto-provides are being added to font packages.
However, those provides are not only useful for auto-installation.
Users are just as interested to know they can use a font package to render Greek or Catalan or Arabic when browsing the package repository manually.
Please transform those provides in user-friendly information added to font package descriptions in packagekit GUI frontends.
We moved the upstream bugtracker to GitHub a long time ago. If this issue still affects you please re-create the issue here: https://github.com/hughsie/PackageKit/issues
Sorry for the impersonal message, and fingers crossed your issue no longer happens. Thanks.
