[Launchpad Bug Tracker]

This bug was fixed in the package libcamera - 0.7.0-1ubuntu2

---------------
libcamera (0.7.0-1ubuntu2) resolute; urgency=medium

  * d/p/fix_pisp_cfe_entities.patch: Allow both old and new CFE
    entity match strings so camera modules can be detected on
    Raspberry Pi 5 using libcamera0.5 (LP: 2110144)
  * d/p/add_syncmode_and_tensors.patch: Add SyncMode controls
    and CNN Tensors to enable rpicam-apps (LP: #2141307)
    - This patch adds the SyncMode IPA controls and the IMX500 tesnors
      and camera data required for rpicam-apps on the Raspberry Pi.

libcamera (0.7.0-1ubuntu1) resolute; urgency=medium

  * debian/control:
    - build without libtensorflow-lite-dev on arm for now since that
      library is in Ubuntu universe.

libcamera (0.7.0-1) experimental; urgency=medium

  [ Dylan Aïssi ]
  * New upstream version 0.7.0
  * Bump SONAME to libcamera0.7
  * Add libtensorflow-lite-dev in Build-Depends for arm64 armhf,
    this is required to enable the Raspberry Pi Neural Network AWB algorithm.
  * Add patch fixing detection of system tensorflow-lite.
  * Remove ppc64el-fix-ftbfs-gcc.patch, no longer required.
    The build was successful on ppc64el via debusine without this patch.
  * Remove redundant:
      - Rules-Requires-Root: no
      - Priority: optional
  * Bump Standards-Version to 4.7.3

Bug description:
  On a Raspberry Pi 5, running the nightly of Ubuntu 26.04 Desktop, I
  installed `rpicam-apps`. There is a Raspberry Pi Global Shutter camera
  connected. `rpicam-hello` fails to start up.

  This worked on 25.04 Desktop.
