[Bug 1993318] Re: ZFS + Encryption installations of Ubuntu Desktop suffer various severe problems related to the package manager

[Brian Murray]

Rebooting after install I noticed that /var/lib/dpkg/ and /var/lib/apt/
are both empty in the installed system.

Title:
  ZFS + Encryption installations of Ubuntu Desktop suffer various severe
  problems related to the package manager

Status in ubiquity package in Ubuntu:
  New
Status in zfs-linux package in Ubuntu:
  New
Status in zsys package in Ubuntu:
  Incomplete

Bug description:
  This is *probably* the wrong package, but it's the best I can figure
  for this, so here goes.

  Hardware: Kubuntu Focus XE, 32 GB RAM, 1 TB SSD, 11th Gen Intel Core
  i5, UEFI, no secure boot. Testing done in GNOME Boxes, BIOS, 4 GB RAM,
  50 GB disk space . OS is Ubuntu Desktop, Kinetic Final ISO.

  Steps to reproduce:

  1. Boot the Ubuntu desktop ISO.
  2. Select "Install Ubuntu" and proceed with the installation process.
  3. When you get to the "Installation type" screen, select "Advanced Options", and enable ZFS + Encryption.
  4. Proceed with the rest of the installation as normal.
  5. Reboot into the newly installed system.
  6. Log in.
  7. Run "sudo apt update" in a terminal.

  Expected result: The package database should be updated normally.

  Actual result: You are presented with the following errors at the end
  of the apt output:

  Reading package lists... Error!
  E: flAbsPath on /var/lib/dpkg/status failed - realpath (2: No such file or directory)
  E: Could not open file  - open (2: No such file or directory)
  E: Problem opening 
  E: The package lists or status file could not be parsed or opened.

  
  Notes: Switching to a TTY will print a crash error message related to the same missing /var/lib/dpkg/status file. Running "sudo touch /var/lib/dpkg/status" will allow "sudo apt update" to function and fix the crashed process in the TTY.

  Once you log in, you'll notice that Firefox is missing (bug #1993279),
  and you will likely be presented with a ton of error messages and
  other scary junk. At least one of those error messages was related to
  update-manager in my experience, and another one was from "check-new-
  release-gtk".
