upgrade 22.04.02 failed. Is the kernel missing raid drivers ? ALERT uuid not found

cc flag

dual ssd RAID1 / stripping.

Hi,

just triggered upgrade from previous version as requested by my Ubuntu OS.

Default install, system won't start. The repartition, clean everything, start from scratch, same result. Dead system.

After a few ACPI errors, new, this was not happening before, I end up in a screen with a (initramfs) prompt.

there is an ALERT message with UUID= ....... does not exist dropping to shell.

After 12 hours of research and tests I am starting to think the issue is that the drivers for the SW RAID are not installed. Thus the boot disk/partition cannot be found.

I am currently in a dead end.

Any advise appreciate. Even if it is to go back to an older version and ignore 22.04 completly.

is the issue related to dmraid not being included ? if yes ? how can I include it ?

Thanks.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
