The Workstation live image Welcome screen (data/liveinst/gnome/fedora-welcome , in the anaconda git tree) uses the 'media-cdrom' icon for the 'Try Fedora' button: tryContent.add(new Gtk.Image({ icon_name: 'media-cdrom', pixel_size: 256 })); tryContent.add(makeLabel(_("Try Fedora"), true)); that icon is part of gnome-icon-theme-legacy: [adamw@adam spin-kickstarts (f20 %)]$ rpm -qf /usr/share/icons/gnome/256x256/devices/media-cdrom.png gnome-icon-theme-legacy-3.12.0-1.fc21.noarch In Fedora 20, gnome-icon-theme-legacy is on the live image, I believe because Rhythmbox required it. However, in current Rawhide, gnome-icon-theme-legacy is no longer pulled into the live images by anything, so the Welcome screen is entirely missing an icon for the "Try Fedora" button. Either anaconda-core should Requires: gnome-icon-theme-legacy , or we should use an icon from one of the icon themes that is still installed - one from gnome-icon-theme would be safest, also installed at present are gnome-icon-theme-symbolic , gnome-icon-theme-extras , and adwaita-icon-theme .
media-cdrom is actually simply a symlink to media-optical , which is part of gnome-icon-theme . so s/media-cdrom/media-optical/ would be the simplest fix. but I think gnome-icon-theme is supposed to go away in favour of adwaita-icon-theme at some point. adwaita-icon-theme has a symbolic version of media-optical (media-optical-symbolic), but not a 'regular' version at present.
Created attachment 903023 [details] [PATCH] fedora-welcome: Correct an icon name after the switch to Adwaita
Thanks for the patch. Pushed.
I believe this is now resolved, last live image I built had the icon back.
