Description Nick 2019-02-12 13:50:11 UTC

SUMMARY
I am running KDE Neon on an encrypted LVM. Each time I boot I am prompted to enter my password to decrypt the disk, and the prompt contains some images and text.

This morning I upgraded to KDE Plasma 5.15 (my laptop is now fully updated) and on reboot the LVM password prompt no longer has any text. The prompt still works when I enter my password but it initially looks like a crash due to the lack of text!

STEPS TO REPRODUCE
1. Upgrade to KDE Plasma 5.15 from 5.14.5 on KDE Neon on an encrypted LVM.
2. Reboot
3. Notice the missing text when the password prompt appears.

OBSERVED RESULT
No text on password prompt (see attached photo)

EXPECTED RESULT
Text to be visible on password prompt.

Please edit /usr/share/initramfs-tools/hooks/plymouth_breeze

and put 

#!/bin/sh
set -ex

at the very top of the file and save it. Then run `sudo update-initramfs -u` and post to the output of that command here.

Hi Harald. Here is the output:

Thanks. Please install the package plymouth-label and check if that fixes your issue.

Comment 5 Nick 2019-02-12 14:24:11 UTC

That worked. 

Interestingly I ran a sudo apt autoremove after updating to 5.15 which, amongst other packages, deleted plymouth-label:

Perhaps this was not a good idea...?!

Comment 6 Harald Sitter 2019-02-12 14:25:34 UTC

Yeah, unfortunately some issues sneaked into a merge we did prior to 5.15.
