I upgraded my system from the command line using dnf system-upgrade. However, after the upgrade, each time I open the Discover app or click the “Refresh” button on the Updates tab, I get the following error message:
I don’t know what’s wrong or how to fix it, but attempting to further upgrade with dnf system-upgrade tells me I’m already on version 44 and need to specify a releasever greater than my current one. What can I do about this?
I recommend you use the command lines tools to do the upgrade.
Using these tools you will either have sucess or see actionable error messages.
