I'm using Ubuntu 20.04 and it's my main OS (No other OS installed except for Ubuntu)
When I try to uninstall Oracle VirtualBox 6.1 it says that there are VMs running even though there aren't (I checked all the processes running at the time)
I screenshotted this after trying to uninstall VirtualBox 6.1 and it keeps happening with every command that tries to remove it:
I already tried running these commands:
sudo apt-get purge virtualbox-6.1:amd64
sudo apt-get --reinstall install virtualbox
sudo apt-get remove virtualbox-6.1
And as you can see from the commands listed I even tried reinstalling it
And even in the Ubuntu Software app it says that there are no packages to remove
Unable to remove "Oracle VM VirtualBox": no packages to remove
