@jack do I need to: 1) download a new ISO and then rebuild from the newer ISO, or can I 2)rebuild with AlmaLinux 8.3 with my already downloaded ISO from two weeks ago machine and upgrade successfully to kernel-4.18.0-240.22.1?
I tried a rebuild last night with the two-week-old ISO and upgraded again. I just rebooted, finally, and the machine still has the
FATAL: FIPS integrity test failed.
I tried to do what this Red Hat Access article (https://access.redhat.com/solutions/3552141) suggested, changing for kernel versions, but it did not work.
I also found this article (https://www.suse.com/support/kb/doc/?id=000018548) for the same problem with openSUSE, it also did not work.
Then I read the bug tracker page (https://bugs.almalinux.org/view.php?id=62), which in conjunction with the Red Hat Access Portal link mentioned above and finishing with this syntax from the Bug Tracker I was able to get my machine to boot without issue (permanently).
This was the command I used to polish off the solution:
sha512hmac /boot/vmlinuz-4.18.0-240.22.1.el8_3.x86_64 > /boot/.vmlinuz-4.18.0-240.22.1.el8_3.x86_64.hmac
