Bug 5793

Summary: F33: Uninstallation of Virtual Box does not have proper auto-remove functionality; leaves behind a tainted kernel in its wake.

Description Andrew Thurman 2020-10-14 22:42:38 CEST 
Steps to reproduce:
1. Install VB (cli or gui/GNOME software)
2. Application + Out of tree kernel modules (VirtualBox-kmodsrc VirtualBox-server akmod-VirtualBox kmod-VirtualBox-5.8.14-300) install like normal.
3. Uninstall application (cli or gui)

Expected result: VB is removed, including all orphaned deps and out of tree/tainted modules.

Actual Result: VB leaves behind tainted modules ~~possibly~~ probably unbeknownst to the end user, until at least a kernel panic/oops.

Temporary fix: ` sudo dnf remove VirtualBox-kmodsrc VirtualBox-server akmod-VirtualBox`

You may also need to include `kmod-VirtualBox-YOURKERNELVERSION-300`

Note: `dnf autoremove` does not work

dnf remove  VirtualBox-server  removes all kmods 


Removing:

Removing dependent packages:
 VirtualBox                                      x86_64 
 VirtualBox-webservice                           x86_64 
 akmod-VirtualBox                                x86_64  
 kmod-VirtualBox-5.8.12-100.fc31.x86_64          x86_64  
 kmod-VirtualBox-5.8.13-100.fc31.x86_64          x86_64

Then I feel like `VirtualBox` shouldn't be the AppStream package, but rather `VirtualBox-server`. If you don't have proper dependency management in GUIs, you shouldn't include the AppStream metadata. I'm not a package mainatiner so maybe I'm talking BS, but it just feels like what's best for the end user experience.

VirtualBox is the Qt part (graphics), which of course needs the server package , but server package doesn't need the graphics package .

I think VirtualBox-kmodsrc will stay behind, maybe there is a need to enforce a dependency so it get removed if uneeded also...

I would suggest to use something like: with fedora or rhel>7
%package kmodsrc
...
Requires: VirtualBox-server = %{evr} or VitualBox-guest = %{evr}

(to be tested)
