[Bug 2046570] Re: package initramfs-tools 0.140ubuntu13.4 failed to install/upgrade: installed initramfs-tools package post-installation script subprocess returned error exit status 1

Thanks. That allows debugging. Which plymouth packages do you have
installed? Please post the output of "dpkg -l | grep plymouth". Can you
also post the output of "update-alternatives --query default.plymouth"?

Analysis:

The script uses the Value field from the "update-alternatives --query
default.plymouth" output to determine the theme. In this case it's
/usr/share/plymouth/themes/bgrt/bgrt.plymouth which then maps to
THEME=bgrt and then to currthemes="bgrt ubuntu-text spinner". The
failing code is:

for currtheme in $currthemes
do
	[...]
	MODULE="${PLUGIN_PATH}/$(sed -n 's/^ModuleName=\(.*\)/\1/p' ${THEMES}/${currtheme}/${currtheme}.plymouth 2>/dev/null || true).so"
	[...]
	# copy plugin and images for current theme
	copy_exec "${MODULE}"

The script derives MODULE=/usr/lib/x86_64-linux-gnu/plymouth//two-
step.so from reading /usr/share/plymouth/themes/bgrt/bgrt.plymouth
(which is shipped by plymouth-theme-spinner), but fails to copy
/usr/lib/x86_64-linux-gnu/plymouth//two-step.so (which is shipped by
plymouth-theme-spinner as well). The shipped files between focal and
jammy hasn't changed.

So the installed plymouth-theme-spinner seems to be broken.
