I am having the same problem. Ubuntu 18.04 installed with Windows 10 as dual boot. Secure boot enabled. The system has been working for years like this (since before 16.04). I have updated to every release since and it was working on all of them. It even worked on 18.04 before the latest kernel update. I suspect a work around could be to downgrade to a previous kernel or to disable module signing, but we should not have to.
I sign my own modules with the following: (only required once) openssl req -new -x509 -newkey rsa:2048 -keyout MOK.priv -outform DER -out MOK.der -nodes -days 36500 -subj "/CN=Descriptive common name/" After every kernel upgrade I sign the modules with: #!/bin/bash for f in $(dirname $(modinfo -n vboxdrv))/*.ko; do echo "Signing $f"; sudo /usr/src/linux-headers-$(uname -r)/scripts/sign-file sha256 ./MOK.priv ./MOK.der $f; done modprobe vboxdrv The kernel upgrade to 4.15.0-22 broke this process. Now the install of virtual box will stall on the following: Building initial module for 4.15.0-22-generic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1775672 Title: virtualbox-dkms installation hangs in 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1775672/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
