I don't know of a general way to flash HP consumer machine firmware directly from Linux, but as a second-best, it is at least possible on the machine that I needed to update (an HP Envy 700-060ea) without the use of Windows (e.g. with only Linux installed on the machine).
First I extracted the HP softpaq:
wine Downloads/sp72302.exe /e /f z:hpbios

I had the same issue OP had when updating from 18.04 LTS to 20.04 LTS (x86_64 machine):
What worked for me was:
I've ran release upgrade and got error messages OP had:

I've check which packages were "foreign" in /var/log/dist-upgrade/main.log:
$ grep Foreign /var/log/dist-upgrade/main.log

I was facing the same error on WSL2 Ubuntu and tried to install ca-certificates with no luck, as it was already installed.
Then I updated /etc/apt/sources.list to use the global servers, updated Apt, and now it works. After upgrading, I saw some updates were made in the /etc/ssl/certs directory; new certificates.
Out of curiosity, I changed sources.list file ...
That package, vulkan-utils does not exist in any of the supported release.
You probably want vulkan-tools instead, which is in the repositories, and ...

utilities for Vulkan, including vulkaninfo.
Supporting this question - since the OP tries to run his old hardware on a current Linux I'd like to mention that an old NVIDIA driver (which needs to be used by that hardware) does not necessarily work with the actual kernel. The question has been asked and answered here already and should be taken into consideration.

Ubuntu 20.04 LTS was released in 2020-April with 5 years of standard support; followed by a further 5 years of extended support (once you enable ESM), so you're asking for something that will work in 2030-May?
The ESM currently cannot be setup; so you can't currently arrange the second 5 years of support - let alone whatever occurs between 2025 and 2030.

What is Firmware?
Many devices have two essential software pieces that make them
function in your operating system. The first is a working driver,
which is the software that lets your system talk to the hardware. The
second is firmware, which is usually a small piece of code that is
uploaded directly to the device for it ...
The error you are encountering is correct and expected behavior. You are attempting to release-upgrade to a release that is already past End Of Life (July 2021); those repositories were withdrawn.
There is no constant, tested migration/upgrade path from an LTS release to a non-LTS release. When the calendar is unfortunate (like now) the tested and supported ...
APT relies on fcntl(2) locking; since ubuntu does not provide an fcntl lock command, you may use fcntl-lock utility for locking (a clone of Peter Anvin's flock command, slightly outdated, though).

# fcntl-lock is a fcntl() clone of H. Peter Anvin's flock(1)
I was getting this report in the PlayOnLinux debugger. I ended up switching to the recommended Nvidia driver and then uninstalling the default graphics driver. I then reinstalled the Nvidia graphics drivers through Synaptic Package Manager and that stopped the madness.
I don't know how the inner workings of the library linking is established but the Nvidia ...

First, excuse me if I am making a wrong assumptions here. I assume you have Thunderbird 78 installed via the Ubuntu package manager and you want to upgrade to Thunderbird 91.
There are, at least, five ways, in principle:
Remove the apt version, and install the Thunderbird 91 snap, by choosing the "candidate" channel instead of "stable". ...
Thanks @clover. This fixes it:

git clone https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
go to the firmware directory:
backup the existing firmware:
sudo mv i915 i915.orig
then (still in /lib/firmware)copy the new firmmware to the same directory:
sudo cp -r ~/linux-firmware/i915/ ...
So you are running 64-bit Ubuntu 20.04 LTS. You can restore default APT repositories using the following single long command:

deb http://security.ubuntu.com/ubuntu/ focal-security main universe multiverse restricted
This will occasionally happen when your apt lists are incomplete or broken. You can rebuild them like this:
Open Terminal (if it's not already open)
Remove the contents of the lists directory:

Rebuild the lists:
sudo apt clean
sudo apt update
Update your system:
sudo apt dist-upgrade

The Ubuntu (21.04) package command-not-found contains /etc/apt/apt.conf.d/50command-not-found which makes apt(8) check for the c-n-f Metadata entries in the repositories when updating.
If this is installed, bash(1) & zsh(1) shells will produce a suggestion along with the error message for missing commands, e.g.:

For me this error message was accompanied by another one:
