I can reproduce the issue when install 18.04 with HWE, the workaround(Kill the dmsetup process or add GRUB_DISABLE_OS_PROBER=true to the kernel options) can works.
Whether will build the new os-prober(1.75) for fixing this issue or not? If yes, what is the schedule? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1663645 Title: Installation hangs at 66% "Installing GRUB boot loader" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/os-prober/+bug/1663645/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
