inclusion of the package on the iso is one thing; it is a different thing to build the boot initrd with microcode included. I do not believe that d-i base installation media ever create d-i initrd with microcode included. Thus even if package is included on the ISO it will not be present in the d-i initrd.
Live based isos all should have microcode in the initrd they boot. Given that the boards are buggy, it's best to download the firmware update from your motherboard manufacturer to update the firmware & cpu microcode of the board itself using like Freedos boot. Then from that point on, all/any boots and installs of anything will at least have working microcode. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1938588 Title: Ubuntu Server 18.04.5 install fails: TSC_DEADLINE disabled due to errata To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-meta/+bug/1938588/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
