usb-creator-gtk uses icon names like "gtk-dialog-info", "gtk-dialog- warning", "gtk-dialog-error", which are not standard icon names as part of the spec: https://specifications.freedesktop.org/icon-naming- spec/latest/#names
The Humanity icon theme provides these icons, but Ubuntu Desktop 25.04 is no longer pre-installing Humanity. Yaru, which falls back to Humanity for missing icons, does not provide these icons. usb-creator should either provide those icons itself, or use standard icon names, which in these case map 1:1 gtk-dialog-info -> dialog-information gtk-dialog-warning -> dialog-warning gtk-dialog-error -> dialog-error -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2104374 Title: Missing icon in the "Installation is complete" dialog To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/usb-creator/+bug/2104374/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
