[Bug 2063887] [NEW] debsums warning after upgrade to Ubuntu 24.04 (noble): changed file /etc/X11/xorg.conf.d/99-v3d.conf (from ubuntu-raspi-settings-desktop package)

Fri Apr 26 21:20:17 UTC 2024

Public bug reported:

System: Raspberry Pi 4 Model B Rev 1.4

After upgrade to Ubuntu 24.04 (noble) I'm getting this debsums warning:

# debsums -sa ubuntu-raspi-settings-desktop
debsums: changed file /etc/X11/xorg.conf.d/99-v3d.conf (from ubuntu-raspi-settings-desktop package)

The difference between the file installed and the file from the ubuntu-
raspi-settings-desktop package is just the indentation:

- The file installed is indented with two spaces:
Section "OutputClass"
  Identifier "vc4"
  MatchDriver "vc4"
  Driver "modesetting"
  Option "PrimaryGPU" "true"
EndSection

- The file from the package is indented with one tabulator:
Section "OutputClass"
      Identifier "vc4"
      MatchDriver "vc4"
      Driver "modesetting"
      Option "PrimaryGPU" "true"
EndSection

If I replace the file installed with the one from the package in order
to avoid the debsums warning, the file is auto-replaced again during
boot by the systemd update-v3d-config.service.

This service runs the script /usr/bin/update-v3d-config; when the system
is a Raspberry Pi 5 this script replaces "Identify" and "MatchDriver"
but for the rest of Raspberry Pi models it should leave the file as
originally was. The problem is that the script always replaces the file
with two spaces indentation instead of one tabulator causing the debsums
mismatch:

...
    sed -e "s/IDENTIFIER/${IDENTIFIER}/; s/DRIVER/${DRIVER}/" << EOF > "$TMPFILE"
Section "OutputClass"
  Identifier "IDENTIFIER"
  MatchDriver "DRIVER"
  Driver "modesetting"
  Option "PrimaryGPU" "true"
EndSection
EOF
    mv "$TMPFILE" "/etc/X11/xorg.conf.d/99-v3d.conf"
...

I understand that this fix is done in every boot because we (users)
should use the same OS installed media  with different Raspberry Pi
models.

Well... a possible solution is to change the package file to have two
spaces of indentation instead of a tabulator, or to change the script to
use a tabulator instead of two spaces. The objective is having both
files identical to avoid the debsums warning... But unfortunately this
"fix" only avoids the debsums warning for the systems that are not a
Raspberry Pi 5 because in that case the warning is unavoidable as the
result installed file will be always different from the one of the
package. So this isn't a perfect solution.
