Title:
  package initramfs-tools 0.137ubuntu12 failed to install/upgrade:
  installed initramfs-tools package post-installation script subprocess
  returned error exit status 1

Status in initramfs-tools package in Ubuntu:
  New

Bug description:
  (1) Command: lsb_release -rd
  Description: Ubuntu 20.10
  Release: 20.10

  (2) Version of Package:
  Ubuntu Software version 3.38.1

  (3) I expected to go through normal updates/upgrades process, but
  instead -

  (4) encountered error messages regarding:

  needrestart is being skipped since dpkg has failed
  E: Sub-process /usr/bin/dpkg returned an error code (1)

  I tried following several threads with suggestions on how to possibly
  clear or repair the issue by applying:

  sudo apt clean
  sudo apt autoremove --purge
  sudo apt upgrade
  sudo apt-get install -f
  sudo dpkg --configure --pending
  dpkg --audit
  sudo update-initramfs -u -k all

  Everything seems to return to "E: Sub-process /usr/bin/dpkg returned
  an error code (1)"
