[Bug 2012670] Re: plymouth: font missing at decrypt root prompt

[Carlos Nihelton]

I got squares on my prompt. I use ZFS on root with native encryption.
The new font is missing in the initramfs.

lsinitramfs -l /boot/initrd.img-6.2.0-18-generic | grep font | grep ubuntu
drwxr-xr-x   2 root     root            0 Mar 23 17:26 usr/share/fonts/truetype/ubuntu


After updating the plymouth hook `/usr/share/initramfs-tools/hooks/plymouth` to copy the new font files (lines 138 to 143) I got the expected behavior.

lsinitramfs -l /boot/initrd.img-6.2.0-18-generic | grep font | grep ubuntu
drwxr-xr-x   2 root     root            0 Mar 23 17:58 usr/share/fonts/truetype/ubuntu
-rw-r--r--   1 root     root       171816 Nov 21 16:54 usr/share/fonts/truetype/ubuntu/UbuntuMono-Italic[wght].ttf
-rw-r--r--   1 root     root       685020 Nov 21 16:54 usr/share/fonts/truetype/ubuntu/Ubuntu[wdth,wght].ttf


Thanks @seb128 for the guidance.
