Snaps, flatpaks, junk like this. I might as well quit fooling with Linux at all. It used to be far superior to Windows. Can’t say that anymore. I DO know what I’m saying. I’ve been a professional UNIX, Linux, *BSD developer for almost 25 years. Oracle’s purchase of Sun Microsystems and the “Solaris” marks the beginning of the down-turn. Should have jumped to Mac at that point I guess. One thing for sure. RH/Fedora/CentOS is off the menu in the interim. This is unacceptable - even to a non-professional.
You can try to boot an older kernel and disable secure boot for the guest at least until the issue with signature verification is resolved.
In a long term, I recommend migrating to QEMU/KVM+libvirt as a more stable and reliable virtualization solution.
This may be related to the common issue here since the kernel module for VirtualBox is a 3rd party module.
If it is then following the steps in the workaround there should fix it.
The package name to remove would be kmod-VirtualBox-6.6.8-200.fc39.x86_64 if you are using the 6.6.8 kernel, or replace the kernel version with whatever kernel you are actually running. Then rebuild that module with the sudo akmods --force as shown in the workaround and VB should be back to functional after a reboot.
The vboxguest module is normally provided by the kernel project, but it seems that vboxguesthas tainted the kernel, which means that this module is not the fedora provided version.
Yes, it seems Ranty conflatulated a few things as neither snaps nor VirtualBox are “RH/Fedora/CentOS” and Oracle lives somewhere else.
QEMU/KVM+libvirt is the best recommendation on Fedora. With everything else you get the “third part experience” that you asked (VMware resp. Oracle) for.
Yep. I know it. I was just frustrated and blowing off steam. Not fair to you guys/gals at all. Please accept my sincere apology for my inappropriate remarks.
