Hi all, I just encountered the same bug while attempting a fresh install of jessie. For me, the solution was to install the lvm2 package from a livecd:
- Make LVM volumes available: $ vgchange -ay - Mount the necessary filesystems $ mount /dev/[...]-vg/root /mnt $ mount -t proc none /mnt/proc $ mount --bind /dev /mnt/dev - If you have a separate boot partition $ mount /dev/[...] /mnt/boot - chroot and install lvm2 $ chroot /mnt $ apt-get install lvm2 If all goes well, this should create a working initramfs. HTH! Regards, Job
