Re: Possibly broken Grub or initrd after updates on Testing

Could you post the new grub.cfg file, so that people running testing,
and following along the thread later, can see how boot-repair fixed it?

Cheers,

Let's hope the mailing list let's this go through.


Keep in mind, this is based on the assumption that your whole / partition is LUKS encrypted (in my case now LUKS2). "root-partition-UUID" is the UUID that's shown in Disks or on the Grub screen for the decryption password prompt. Now, I can't say for sure what "root-partition-UUID2" is, but that's what seems to be symlinked to /dev/dm-0 and with blkid, one of the entries will look like this:


/dev/mapper/luks-<root-partition-UUID>: UUID="<root-partition-UUID2>" BLOCK_SIZE="4096" TYPE="ext4"


So maybe it's just some kind of virtual UUID for the decrypted root partition.
