Hi. I don't think this is a grub-installer issue so I've moved it over to Subiqutiy, as it looks like that is what you're trying to do here.
So to confirm for BOTH 20.04 and 20.04.2, you are using the new Subiquity installer (The Ubuntu Server Live ISO available from ubuntu.com)? Does the machine have internet access during installation? ** Package changed: grub-installer (Ubuntu) => subiquity (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1934755 Title: Ubuntu server 20.04 installation will crash with http error 500 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/subiquity/+bug/1934755/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
