I've tried using Virtualbox 6.1.14 from this PPA - https://launchpad.net/~costamagnagianfranco/+archive/ubuntu/virtualbox- ppa in both host and guest.
This seems to fix the problem. I did experience another problem but not sure if appropriate to bug as running from the PPA. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1893957 Title: Ubuntu 20.04 guest aborts on graphical login following recent upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1893957/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
