plymouth hook in initramfs needs font but doesn't Depend on it

The bug is that the hook merged from Debian has clobbered the logic to use the Ubuntu fonts (which are depended on) instead of DejaVu.

Status changed to 'Confirmed' because the bug affects multiple users.

This bug has been reported on the Ubuntu ISO testing tracker.

A list of all reports related to this bug can be found here:
http://iso.qa.ubuntu.com/qatracker/reports/bugs/1592405

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.

Simple fix is to bump "fonts-deja" to be a dependency?

fonts-dejavu is still a "recommended" but not installed package.

from this daily bionic lubuntu alternate iso:
http://cdimage.ubuntu.com/lubuntu/daily/20180303/bionic-alternate-amd64.iso

from /var/log/syslog of the install:

Mar 3 21:28:35 main-menu[4087]: (process:18437): update-initramfs: Generating /boot/initrd.img-4.15.0-10-generic

work around is to manually:
apt-get install fonts-dejavu

Making it a dependency is NOT the correct solution for this bug. The
correct solution is to fix the initramfs script to use the Ubuntu fonts
instead, which is what we had prior to the Debian merge.

Steve,

I'm all for anything that fixes it.

This may be a really dumb question, but is there any way we could get the patch upstreamed to Debian? So it won't break on a future merge?

Lubuntu Bionic 20180312 still has this issue.

Lubuntu Bionic 20180317 still has this issue.

Whoever works on this bug, please update the dependency to fonts-ubuntu-console instead of the transitional package.

This bug was fixed in the package plymouth - 0.9.3-1ubuntu3

---------------
plymouth (0.9.3-1ubuntu3) bionic; urgency=medium

  * Make the Ubuntu font the default sans-serif & mono fonts. LP: #1592405
  * Adjust title of ubuntu-text theme.
  * In the ubuntu-logo theme fallback to sans-serif font, if Ubuntu font
    is not available.

I retested bionic lubuntu alternate 20180401. This iso includes "plymouth 0.9.3-1ubutu4". Note: this version of plymouth ends in ".4" and not the ".3" version mentioned in comment #11.

When I reviewed the syslog from the install there are still errors with the update-initramfs due to the missing font file.

I think .4 is an upstream merge from Debian?:
http://changelogs.ubuntu.com/changelogs/pool/main/p/plymouth/plymouth_0.9.3-1ubuntu4/changelog

Did version .4 undo the fixes in the .3 version?

Can you please attach said syslog?

The hook is still trying to copy dejavu fonts into the initramfs.

Which is correct! We still do need a serif font.... and a fallback
font for languages not covered by the ubuntu font. Are you implying
DejaVu font is not shipped by default on Lubuntu at all?

We do?

$ grep -ri serif plymouth-0.9.3/
plymouth-0.9.3/debian/changelog: * Make the Ubuntu font the default sans-serif & mono fonts. LP: #1592405

The plymouth initramfs hook has no l10n support.

Probably. Even if it was, it would still be a bug for the plymouth hook to
require it without a dependency.

This bug was fixed in the package plymouth - 0.9.3-1ubuntu5

---------------
plymouth (0.9.3-1ubuntu5) bionic; urgency=medium

  * Move the Ubuntu font, dejavu font, fontconfig dependencies to
    plymouth-label package, such that any "graphical" theme based on
    plymouth label has the right fonts, e.g. the src:lubuntu-artwork
    themes. LP: #1592405

Thank you! :)

lubuntu alternate bionic 20180402 has no errors.
