Fixed up the instructions (forgot to mention that *both* libraspberrypi0 and libraspberrypi0:armhf need installing from -proposed to verify this!). Verification done on Ubuntu Desktop for Pi and Ubuntu Server (arm64) for Pi, on a Pi 400, and a Pi 4B. No issues encountered.
** Description changed: [Impact] Despite libraspberrypi0 being declared Multi-Arch: same, users cannot install libraspberrypi0:armhf on arm64 systems. This affects the ability to (attempt to) use libwidevine (the library required to play certain proprietary streaming services, e.g. Netflix, which is currently only available as an armhf binary). Note: For the sake of clarity, while this fix enables libraspberrypi0:armhf to be co-installed with the arm64 variant, I have *not* tested installation / usage of widevine itself as that's beyond the scope of this bug. It also affects users of the (still very popular) legacy camera stack, which is only supported on the armhf architecture as of jammy (all the mmal utilities and libraries were removed from arm64 upstream, and this change was incorporated in raspberrypi-userland in jammy). [Test Plan] * Flash the Ubuntu Desktop 22.04 for Raspberry Pi to an SD card (http://cdimage.ubuntu.com/ubuntu/releases/jammy/release/ubuntu-22.04-preinstalled- desktop-arm64+raspi.img.xz is the relevant image, but this is probably easier to accomplish via the rpi-imager tool) * Boot the SD card on a supported Pi (4, 400, CM4) and run through first-time setup * Open a terminal * sudo dpkg --add-architecture armhf * sudo apt update * sudo apt install libraspberrypi0:armhf * Observe failure due to conflict in lintian-overrides * Enable proposed updates (https://wiki.ubuntu.com/Testing/EnableProposed) * sudo apt update - * sudo apt install -t jammy-proposed libraspberrypi0:armhf + * sudo apt install -t jammy-proposed libraspberrypi0 + libraspberrypi0:armhf * Package installs successfully * The fixed version also sets Multi-Arch: same on libraspberrypi-dev, so it would also be useful to test the following: sudo apt install libraspberrypi-dev:{armhf,arm64} [Regression Potential] We could backport just the Multi-Arch fixes to the lintian-overrides (an essentially risk-free option, since the only difference would be in the lintian overrides themselves), but the diff between the version currently shipped in jammy, and the fixed version in kinetic is small consisting of only 6 (mostly trivial) commits (no new features are included, just bug fixes). Hence, I've decided to just backport the kinetic version, unless the SRU team raises any objections. The fixed version has been tested on the jammy desktop and jammy server arm64 platforms without issue so far. The regression potential is low; despite it being a new version the delta is (as mentioned) a few largely trivial bug fixes. The extra commits (https://github.com/raspberrypi/userland/compare/14b90ff9d9f031391a299e6e006965d02bfd1bb1...HEAD) in the kinetic version are as follows: 3ff42d69724062cbe4f72d2978ac035550823d10 vcos: Add vcos_safe_strncpy and VCOS_SAFE_STRNCPY -- fixes a complaint from the vc4 linker about not finding strnlen a70a7428f7861d3b8eab24886d48a308936ec912 userland: dtoverlay: Handle parameters in overlay_map -- fixes dtoverlay ignoring parameters from the overlay map affef1eb4f264f4fffa732d9216e4fc1e1b9ac56 dtoverlay: Rebase aliases in overlays like labels -- fixes dtoverlay handling aliases in loaded overlays 09570925bf244f8a041f8b7e88f8f2a6664acbab dtoverlay: Don't mix non-fatal errors and offsets -- fixes an issue (https://github.com/raspberrypi/firmware/issues/1686) with invalid fragments in an overlay breaking boot 8fa944c74085aacd99da3e733af8dc5ac9b04fd9 mmal: Add mapping for IL OMX_IndexParamBrcmEnableIJGTableScaling param -- added a missing MMAL mapping for the legacy graphics stack c4fd1b8986c6d6d4ae5cd51e65a8bbeb495dfa4e Fix declaration of raspicommonsettings_parse_cmdline [Original Description] https://github.com/Botspot/pi-apps/pull/1806 Cannot install libraspberrypi0:armhf on 22.04 (Jammy) because of broken dependencies.
