Ran into this today applying a mass set of updates to an 18.04 system that was last updated sometime last year. Running on a 2007 iMac.
Apple hasn't made firmware updates for this model in years -- and firmware updates require MacOS installed anyway AFIAK -- so that approach is closed to me. That said, David Wilson's workaround at #7 above worked perfectly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1853369 Title: [19.10] Boot hangs at "loading initial ramdisk" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1853369/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
