Description Marc Muehlfeld 2015-11-07 11:26:25 EST
Description of problem:
The command "dnf remove kernel", removes all kernel - including the one, that is currently active. Before F21 and also in RHEL, all kernels will be removed - except the current one. This behaviour should be back, to prevent uninstalling all kernels and can't boot any more.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Have at least two kernel packages installed on your system.
2. Run "dnf remove kernel"

Actual results:
dnf offers to remove all kernel packages - including the one that is currently active.

Expected results:
dnf should skip the current active kernel for removal (like it was before F21 and also is in RHEL)

Additional info:
This bug was already reported for yum in Fedora 21 (Bug #1175532), but this one was closed, because F21 is EOL. I opened a new one, because meanwhile it's dnf and not yum any more.

The running kernel is never removed - protected_packages from dnf-plugins-core component reports it and halts the operation.

I digged a bit deeper and find out, that the "kernel" package doesn't contain any files (any more?):

# rpm -qlp kernel-4.2.5-300.fc23.x86_64.rpm 
(enthält keine Dateien)    -> in english: contains no files

I don't understand the sense of a package without files, but this shouldn't be part of this request :-)

The kernel is inside the package kernel-core. And for that, Jan's reply is correct. The active Kernel isn't removed:

# dnf remove kernel-core
Abhängigkeiten sind aufgelöst.
Fehler: The operation would result in removing the booted kernel: kernel-core-4.2.5-300.fc23.x86_64.

Sorry for the noise. I set the status to NOTABUG.
