Plymouth initramfs hook needs missing dependancy fonts-dejavu-core so update-initramfs fails

[Jb]

Missing font dependency --> plymouth initramfs hook fails --> update-initramfs fails --> new kernel failed to install.

Bionic Lubuntu alternate 20180221

update-initramfs -c -k all

It gives an error:

Rebuilding ramfs...be patient
update-initramfs: Generating /boot/initrd.img-4.13.0-32-generic
cp: cannot stat '/usr/share/fonts/truetype/ttf-dejavu/DejaVuSerif.ttf': No such file or directory
E: /usr/share/initramfs-tools/hooks/plymouth failed with return 1.
update-initramfs: failed for /boot/initrd.img-4.13.0-32-generic with 1.

I checked and the directory /usr/share/fonts/truetype/ttf-dejavu/ does not exist.

Fyi...the 4.15 kernel just came out. This caused the 4.15 kernel to fail to install.

If I apt-get install fonts-dejavu-core it will work around this issue.

If plymouth needs this font, this package should be a dependency.

Note: this same error occurs during the Lubuntu install as seen in /var/log/syslog:

Earlier in the install I see that it says it lists "fonts-deja" as a *suggested* (but not installed) package. fonts-deja includes fonts-dejavu-core and fonts-dejavu-extra.

This should be bumped from a suggested package to a dependency.
