[SOLVED] VirtualBox - NS_ERROR_FACTORY_NOT_REGISTERED (0x80040154)
Another problem.
VirtualBox not start anymore with last update
[2021-10-22T08:52:34+0200] [ALPM] upgraded virtualbox-host-dkms (6.1.28-2 -> 6.1.28-3)
[2021-10-22T08:52:34+0200] [ALPM] upgraded virtualbox (6.1.28-2 -> 6.1.28-3)
report error
$ VBoxManage list vms
VBoxManage: error: Failed to create the VirtualBox object!
VBoxManage: error: Code NS_ERROR_FACTORY_NOT_REGISTERED (0x80040154) - Class not registered (extended info not available)
VBoxManage: error: Most likely, the VirtualBox COM server is not running or failed to start.
the drivers are installed, /tmp it's ok and libraries *.so are ok too.
If I start as root produce another error
$ sudo VirtualBox
Qt WARNING: QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
the dir is created, but empty... the /tmp is a tmpfs declared in the fstab
tmpfs /tmp tmpfs nodev,nosuid,noatime,mode=1777,size=1G 0 0
what's changed in the last update? what's differ from yesterday?

If you didn't reboot you'll likely have to reload the vbox kernel modules and stop crying "sudo" everytime you face an error - typically you're just gonna make things worse.

eh...
I use secure boot and need to reboot if any kernel module changed. 
The modules are loaded correct. I missing something? Systemd service?
I'm criing 'cause i need the vm to work!!!

Why's libvpx not in your list of recent updates?
It was updated 1 minute before virtualbox…

I do not know, it's not listed in the updates
$ cat /var/log/pacman.log |grep libvpx
[2020-10-23T19:46:57+0000] [ALPM] installed libvpx (1.9.0-1)
[2021-03-26T09:45:49+0100] [ALPM] upgraded libvpx (1.9.0-1 -> 1.10.0-1)

Your mirror was probably out of sync.
Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
