tl;dr I hit this error while trying to reinstall grub: grub-probe: error: can't mount encrypted volume '/dev/sda5': no such partition
Hello, we've seen fixes suggested for non-encrypted installs which involve either reinstalling grub or running dpkg-configure grub-pc from chroot. How do we go about fixing an LLVM LUKS encrypted installation though? It's a fairly common way of setting up the desktop I gather as it's the last option on the Debian Installer menu. Here's what I've discovered so far: ---------------------------------------------- fdisk -l /dev/sda - this reveals the default LUKS/LVM setup /dev/sda1 /dev/sda2 /dev/sda5 - further details can be found here, since I tried the Ubuntu boot repair USB but it failed to offer the repair option since I have a /boot directory but it scanned my system paste.ubuntu.com/p/5vpH3rGM9h udisksctl unlock -b /dev/sda5 - enter password here, LUKs partition gets unlocked apt update apt install lvm2 vgchange -ay # makes LVM volumes active udisksctl mount -b /dev/mapper/$HOSTNAME--vg-root ls /media/root/$UUID apt install grub grub-install --root-directory=/media/root/$UUID /dev/sda - here's the main error grub-probe: error: can't mount encrypted volume '/dev/sda5': no such partition - trying the dpkg-reconfigre grub-pc solution gets me no further chroot /media/root/$UUID dpkg-reconfigure grub-pc - I select th defaults in dpkg-configure, which is blank command line then 'quiet' /var/lib/dpkg/info/grub-pc.postint: line 340: /dev/null: Permission denied [ warnings about locale] Can't open /dev/null: Permission denied -------------------------------------------------- I am at an impasse, help? I'm stuck! Todd
