I had the same problem today. I couldn't even uninstall the original VirtualBox using apt or the software center. I had to use:
sudo apt-get purge virtualbox* and then reinstall the latest virtualbox 6.1.16 from their website. I couldn't figure out why Virtualbox worked yesterday and had errors today. Hope this helps someone! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1891916 Title: virtualbox-dkms 6.1.10-dfsg-1~ubuntu1.20.04.1 fails to build with kernel 5.8 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1891916/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
