I have done a standard Linux Mint install with encryption and LVM enabled. Then I have shrunk that LVM and created a separate /home using this guide such that I could easily reinstall Linux later without having to touch my /home.

Now I want to keep the LUKS and LVM and just reinstall Mint into that LVM, wiping my root directory but keeping /home.

What I've tried:

  • Run the Mint live CD again

  • Unlock my encrypted root and home partitions in nemo

  • Install the new system to the unlocked (encrypted) root partition and mounting all the other partitions/volumes to where they've been before

But after I restart the system, it won't boot and give back the error: "Volume group 'vgmint' not found"

I've found a solution!

Apparently the Ubuntu / Linux Mint installer is currently buggy, but there is an easy workaround.

  • For 20.04-based Mint / Ubuntu installs see the initial post of the before linked website
  • For 22.04-based see post #12 of said website (the author made a mistake in his guide though: instead of sudo cryptsetup luksOpen /dev/sdX sdX_crypt use cryptsetup luksOpen /dev/sdX sdX_crypt. Using sudo will return something like "sudo not found".
  • Whenever you are dropped into initramfs prompt, you are typically already root, so sudo is not necessary. Because of this, there is little reason to include sudo in initramfs at all.
