When attempting to see the updates tab in the software center, I receive the error message shown in the attached image. These problems started occurring after I installed the NVIDIA driver + Control Panel using the commands shown here: [ Howto/NVIDIA - RPM Fusion ] It’s worth noting that I first tried to install them from the software center automatically first, but then uninstalled them because they did not work.
Any help with this problem is much appreciated.
What if you perform the updates from the command line?
sudo dnf update
Do you receive any dependencies error?
I have also checked the directory [ /etc/dnf/protected.d ] to see if “kernel” was listed as protected, but it was not. I’m really not sure why [ dnf update ] fails as shown.
The kernel is a protected package by default, I think.
Btw sorry, but personally I can’t be of help.
You could explore dnf distro-sync, but I don’t guarantee.
1741381 – DNF wants to remove kernel-core suggest that you try: ‘sudo dnf mark install kernel kernel-modules’ that would tell dnf that you specifically had, as a user, requested the kernel and kernel-modules packages, so that solutions it find, should keep them.
Unfortunately, the command [ dnf distro-sync ] returns the same “would remove the kernel” error as the others. I tried [ sudo dnf mark install kernel kernel-modules ] as well, and the command completed successfully, but made no difference in the result of [ dnf update ] or [ dnf distro-sync ].
hum… ‘sudo dnf mark install kernel-core’ ?
Same result as [ sudo dnf mark install kernel kernel-modules ].
A side note, I can still install and remove packages from the store, I just can’t check for updates. I’ve also tried completely removing and reinstalling all NVIDIA-related packages, but to no effect.
What if you try to add verbose flags to dnf?
sudo dnf update -vvv
Have you tried …
dnf clean all before running the update command?
You can use sudo dnf repoquery --unsatisfied to display broken dependencies. May be worth a try.
Finally, I would issue a sudo rpm --rebuilddb to rebuild the rpm database. That may fix your problem.
I just tried both [ dnf clean all ] and [ sudo rpm --rebuilddb ], but the terminal shows the same error. After running [ sudo dnf repoquery --unsatisfied ] with the [ --verbose ] option added to the end, I got this:
The only errors seem to be in the fedora-updates-modular repo, which would explain what’s happening.
Next thing to do is disabling all unused (modular?) and all third-party (adobe, skype, 
) repos and the-run above commands.
Well… playing apprentice wizard: maybe --noautoremove
I tried both commands, but the repoquery gave the same result and the system still won’t update. I’m thinking I may need to completely remove and replace the [ fedora-updates-modular.repo ] file in the [ /etc/yum.repos.d ] folder. How would I go about safely doing so?
I’d like to know the output of “sudo dnf repoquery --whatconflicts kernel-core”.
To safely deactivate some repositories, I think I would launch gnome-software, in upper-right click the icon with horizontal lines, click software repositories, and deactivate one/some repositories. So that you could easily re-“Enable” them later.
