Success!
Here are the steps I used:
VirtualBox failed to open due to some out-of-date end of life thing in
the Ubuntu version of VirtualBox.
Using Synaptic, uninstalled the Ubuntu version of VirtualBox.
Followed instructions at
https://linuxcapable.com/install-virtualbox-on-ubuntu-linux/
Ran
sudo apt update
sudo apt upgrade
sudo apt install dirmngr ca-certificates
software-properties-common apt-transport-https curl -y
curl -fSsL

tee /usr/share/keyrings/virtualbox.gpg > /dev/null
echo "deb [arch=$( dpkg --print-architecture )

/etc/apt/sources.list.d/virtualbox-7.list
sudo apt update
sudo apt install virtualbox-7.0 linux-headers-$(uname -r) -y
apt-cache policy virtualbox-7.0
systemctl status vboxdrv
executed strangely – had to "exit" which closed the terminal
started a new terminal and arrowed up to the status vboxdrv
line and tried again.
Same issue. Exit didn't close the terminal.
Decided to move on to the next step.
sudo systemctl enable vboxdrv –now
Old link (dscktop icon) starts VirtualBox
Downloaded extension pack from
https://www.virtualbox.org/wiki/Downloads
Right-clicked on it and it installed.
Ran
vboxmanage list extpacks
Looks like it installed.
sudo usermod -a -G vboxusers $USER
Had to restart Xubuntu.
Ran
groups $USER
Successful
Started Win10 in VirtualBox
Works as expected.
Done!
Thanks, Tomas, for your help. Thanks PLUG for existing and providing
access to many experienced users.
