Can't. /var/log is in tmpfs and I didn't save them unfortunately. Feel
free to close this as a duplicate of

Title:
  Upgrading from 18.04 to 20.04 encrypted installation with LUKS and LVM
  makes it unbootable without manual intervention

Status in lvm2 package in Ubuntu:
  New
Status in ubuntu-release-upgrader package in Ubuntu:
  Incomplete

Bug description:
  Volume Group metadata had to be upgraded manually with

  vgck --updatemetadata yourvgname

  The VG name was somehow changed from lvm-name to just name and I had
  to edit /etc/crypttab and update-initramfs -u -k all

  Also cryptsetup-initramfs package was deleted for some reason, had to
  re-install it in chroot. Maybe it happened because I have disabled
  installing recommended and suggested packages or maybe because none of
  *buntu-desktop packages are installed on my system. Not sure if I have
  to report it as a separate problem, please advise.
