Initramfs boot stuck

I currently encounter the initramfs on boot "error". I tried several hours to recover from it.

At the first place I got the error, /dev/mapper/root does not exist. I got rid of that with this steps:

  1. Boot into a live distro.
  2. cryptsetup open /dev/nvmexxxx - get access to my nvme.
  3. mount the root, usr, tmp, var, dev, sys, proc and boot into /mnt.
  4. chroot /mnt
  5. execute this command update-initramfs -u -k all and than update-grub as well.
  6. reboot

Now I do not get any alerts at all and the prompt wont show up, where I can enter my password for the nvme to "unlock".

The only clue I have is, when I boot up in recovery mode. Cannot process volume group vg00. I am not able to find anything in the internet about this error. Also I checked my /etc/crypttab as well and there is the right UUID. I also checked /etc/fstab, if I named the tag from cryptsetup wrong, but this neither.

I also tried this bash script, but with no success.

-- Update output of vgdisplay vg00 -- | Name | Name | |:------:|:------:| |VG Name| vg00| |System ID| |
|Format| lvm2| |Metadata Areas| 1| |Metadata Sequence No| 11| |VG Access | read/write| |VG Status |resizable| |MAX LV | 0| |Cur LV | 6| |Open LV | 6| |Max PV | 0| |Cur PV | 1| |Act PV | 1| |VG Size | <476.27 GiB| |PE Size | 4.00 MiB| |Total PE | 121925| |Alloc PE / Size | 121925 / <476.27 GiB| |Free PE / Size | 0 / 0 | |VG UUID | affkCZ-Y9aU-7r3p-dTxo-5Y0A-u91e-Nhubij|

Thank in advance!

Can you add the output of `vgdisplay vg00` to your question?

OK now I got everything to work. The solution below just worked for me, because a new linux version was available.

The solution was:

Do the steps I described earlier and be aware of the naming of the label while executing the cryptsetup open /dev/nvmexxxx command. To be sure, you have the right name, make a look up at /etc/crypttab. It should looks like something like this: label_name UUID=your_id none luks,discard. Write it done or remember the label_name. Reboot the system and manually unlock the disk with the exact same label_name. After that exit and it will boot normally into your OS. In your OS open a terminal and type in sudo apt update && sudo apt upgrade -y. After that run the command sudo update-initramfs -u -k all to update your initramfs. Now it should work.

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.
