1Does this answer your question? ACPI error on every boot – karel Jul 14 '22 at 12:51

@karel I do think it has to do with the latest kernel update…I did try to downgrade to version 20.04 using the usb boot and not setting up wifi in the process, it installed perfectly and all the errors were gone….it was on kernel 5.13 – Michael Collins Jul 15 '22 at 07:03
