  • the removing part is very strange..

first, idk this repo - @koji-override-0 I read a bit about that repo here

but i'm still not sure if that's a good repo - accept the update, or a bad repo - abort the update (and may remove the repo?)

So should I update? Or abort the update and remove this repo?

Because I think, because the names of the packages that will be removed, that if I do accept this update, so it's may remove my kernel? It's sounds weird - why the system will remove his kernel, but that's the name of the packages, so I really don't know..

So what do I need to do? - I'm using fedora 23

The removing part is not too strange. Default settings in Fedora are to keep the 3 most recent kernels. As you add kernels to your system by updating it, dnf starts removing the oldest kernel(s). If you don't want to remove the old kernel(s)/keep a larger amount of kernels on your system, just modify the settings in /etc/dnf/dnf.conf (sudo nano /etc/dnf/dnf.conf or sudo gedit /etc/dnf/dnf.conf). There is a line that says


Change it to whatever number of kernels you want to keep (>2) but be aware that each kernels consumes space on /boot, so don't fill this partition fully up.

You can run the update with no problem.

What you see there in the removing part is the kernel that will be removed. Seems like it was installed from koji build system which is part of Fedora in any case upgrade will work as what you doing is removin a old kernel.

Review your repos to check that nothing points to koji.

Good Luck.
