Created attachment 161744 [details] Error message needs improvement Getting this unhelpful error when starting Discover. What signature? What input is needed? Error messages 101.
Unfortunately this error message comes from the underlying package management system, not Discover. Discover can pass it on to you, but it can't add more information or context where none exists. The problem ultimately comes from the PackageKit plugin provided by whatever distro you're using (or its parent distro, if you're using a distro that's built on top of another one). I wish distros took better care of their PackageKit plugins such that they worked better in general and provided better error messages when they don't, but regrettably many distros do not.
Thanks for clarifying. I was using Fedora 38 with the KDE spin. Where upstream could I report this?
https://bugzilla.redhat.com/ would be a good start. Even better would be if you can make the error message appear by running `pkcon refresh` or `sudo dnf update`, which would prove that the message is coming specifically from the DNF PackageKit plugin.
