[Bug 1973285] Re: [SRU] libraspberrypi0 multi-arch install failing due to lintian override content difference

[Dave Jones]

** 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 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,
+ 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 fixed 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.
