I can reproduce a bug but I want to verify it's the same bug...
When you say:
[Actual result]
Black screen and need to press "Enter" to reboot.
Do you mean a totally "black screen", or one with logos? Because I get
one with logos and that doesn't seem to have anything spinning. Maybe
it's the bgrt theme and not the spinner theme...
Also, the relevant code in casper seems to be unchanged between eoan and
focal:
MSG="Please remove the installation medium, then press ENTER: "
MSG_FALLBACK="Please remove the installation medium, then reboot."
if [ "$prompt" ]; then
if [ -x /bin/plymouth ] && plymouth --ping; then
chvt 63
plymouth message --text="$MSG"
So either:
* one of those commands above are failing; or
* plymouthd is starting too late to receive the commands (a race); or
* there's a bug in plymouthd, but I first need to find out how/where plymouthd is being launched. Any idea?

plymouth spinner can not show the messages after installation.

In Progress
Bug description:
[Summary]
Before 20.04, when user finished the 1st stage of installation, the message 『please remove the installation medium then reboot』or 『please remove installation medium then press enter』 will be shown on the screen.
But since 20.04, due to the using of plymouth-themes-spinner, the
system will still waiting for user to press Enter but without any
message, so the system will be likely hanged there.
[Steps to reproduce]
1. Boot the installer with USB sticker
2. Finish the installation.
3. Click the button on the diagram to reboot.
[Expected result]
System reboot and boot to login page.
[Actual result]
Black screen and need to press "Enter" to reboot.
[Failure rate]
100%
