login loop after security update

[ariel8]

yesterday i installed a security update, it asked me to reboot so i did, it brought me to the login screen and whenever ivtry to log into my user it puts me back, trying to use the guest session brings up a popup in the top left saying "VBoxClient: the Virtualbox kernel service is not running. exiting."

If this is inside a VirtualBox VM then install the dkms package and then reinstall the Guest Additions

If not a VirtualBox VM, what is it then?
What do you mean by "guest session"?

Also, please post the output of running these commands in a Terminal -

lsb_release -a
uname -a

How and why did you install the VirtualBox Guest Additions?
What does that uname command above give?

I don't recall installing them

This would show if it got installed through the package manager

dpkg-query -W | grep -i virtualbox

If it's the official Guest Additions look in /opt for VBox related stuff.

Let us know what you find (especially if you find it in /opt as uninstalling official Guest Additions on a bare-metal machine might be slightly finicky)
