** Description changed:
+ [Impact]
+
+ The 64-bit 18.04 image linked from this page https://ubuntu.com/download
+ /raspberry-pi for Raspberry Pi 3 and 4 fails to boot on my Raspberry Pi
+ 4B (8G RAM). Boot fails with an error screen complaining that it needs
+ newer software.
+
+ This is basically part of the big linux-firmware-raspi2 backport to
+ bionic, but left this bug in the .changes for tracking purposes. See
+ https://bugs.launchpad.net/ubuntu/+source/linux-firmware-
+ raspi2/+bug/1888211 for more info.
+
+ [Test Case]
+
+ Build a new bionic-proposed raspi image, try booting it on a rev 1.4
+ board (e.g. Raspberry Pi 4 8GB).
+
+ [Regression Potential]
+
+ Same as in LP: #1888211.
+
+ [Original Description]

The 64-bit 18.04 image linked from this page https://ubuntu.com/download
/raspberry-pi for Raspberry Pi 3 and 4 fails to boot on my Raspberry Pi
4B (8G RAM). Boot fails with an error screen complaining that it needs
newer software.
The image in question can be found at https://ubuntu.com/download
/raspberry-pi/thank-
you?version=18.04&versionPatch=.4&architecture=arm64+raspi3 , so at
first I figured maybe the wrong one had just been linked from the
downloads page (image for raspi 3 instead of 4), but it has the same
checksum as the image at https://ubuntu.com/download/raspberry-pi/thank-
you?version=18.04&versionPatch=.4&architecture=arm64+raspi4 , so this
seems unlikely.
The 64-bit 20.04 image linked from that same downloads page boots fine.
Most of the text from the error screen:
