I tried Ubuntu for a while, then gave up. However, I do think I'll try it again, and here's why:
When I tried to use it before, I had a class 7 SD card. Now that I have a class 10 SD card, Raspbian/Ubuntu, for that matter, is much snappier. And, instead of a user developed OS, I would use the official Ubuntu from here:

Thanks!...

The RPI4 with the current firmware can boot from USB.. However what I think is happening in your case is it's booting from the SD card then it's remounting the drives of the USB drive.
In RPIOS the SD card boot partition cmdline.txt contains the UUID of the root file-system. But Ubuntu uses a label 'Writable'.
You can view the label and UUID information ...

I think Ubuntu 20.04.2 is better than 18.04.

It depends on how you have setup networking.
Routing will use the default route with the highest priority.

Here is my script that puts things together: Gist link: Install RealVNC server on arm64 Linux
mkdir realvncserversetup && cd realvncserversetup
echo Add armhf arch
sudo dpkg --add-architecture armhf && sudo apt update
echo Download and install RealVNC server
wget -nv https://www.realvnc.com/download/file/vnc.files/VNC-Server-6.7.4-Linux-ARM....

It is possible to set gpu_mem to larger values, however this should be avoided since it can cause problems, such as preventing Linux from booting.
The minimum value is 16, however this disables certain GPU features.
Memory options in config.txt

I have set GPU memory to 1 MB in raspi-config and official Raspberry PI OS. 0 MB didn't work when I've tried to set.
I've no monitor connected and only connecting via SSH. This works flawlessly.

First, as indicated in this link one can inspect which kernels are installed using:
dpkg -l | grep linux-image
which can return something like:
.. linux-image-5.11.0-1007-raspi ..
.. linux-image-raspi ..
which I believe are kernel versions.
Next one can set these kernel versions to hold using the interpretation of the commands from this link:
sudo -s
echo ...

Description
This script named first_run.sh asks you for your wifi ssid and wifi password and automatically connects your Raspberry Pi 4 to your wifi:
Code
# Verify internet access is available
while [ $(ping -q -w1 -c1 google.com &>/dev/null && echo online || echo offline) == offline ]
do
sleep 1
# get wifi module
module=$(ls /sys/...

You could use pip to install 1.6.2 from pypi.org
https://pypi.org/project/gpiozero/
pip install --force-reinstall gpiozero
I don't know how that will play with your existing install.
