Description Lukas Brabec 2019-11-07 13:34:20 UTC 
I tried to reproduce bug reported on r/Fedora (https://www.reddit.com/r/Fedora/comments/dsv563/something_tells_me_this_isnt_supposed_to_happen), the original reporter on reddit saw a prompt to actually remove all kernels, for the bug I encountered see below.


After clean installation of Fedora 31, "dnf autoremove" will result in output:

$ sudo dnf autoremove
...
Dependencies resolved.
Nothing to do.
Complete!



Output after running "dnf update kernel" and reboot:

$ sudo dnf autoremove
Last metadata expiration check: 0:02:52 ago on Thu 07 Nov 2019 02:12:03 PM CET.
Error: 
 Problem: The operation would result in removing the following protected packages: kernel-core
(try to add '--skip-broken' to skip uninstallable packages)



Output after "dnf update" and reboot:

$ sudo dnf autoremove
Last metadata expiration check: 0:07:42 ago on Thu 07 Nov 2019 02:12:03 PM CET.
Error: 
 Problem: The operation would result in removing the following protected packages: kernel-core
(try to add '--skip-broken' to skip uninstallable packages)

With cooperation with Dan Mach we created patches (https://github.com/rpm-software-management/dnf/pull/1529) that resolve the issue.

As a workaround I would recommend to mark kernel and kernel-core as user-installed packages (dnf mark install kernel kernel-core).
