Public bug reported:
In a raspberry pi system running 18.04, when running "do-release-upgrade -d" to
upgrade to 20.04.1,
the transition from linux-raspi2-hwe-18.04 to linux-raspi doesn't seem to be
done correctly and the system ends up without this and the linux-headers-raspi
meta packages.
These are the meta packages installed before the release upgrade:
ii linux-headers-raspi2-hwe-18.04 5.3.0.1017.6
arm64 Linux kernel headers for Raspberry Pi systems.
ii linux-image-raspi2-hwe-18.04 5.3.0.1017.6
arm64 Linux kernel image for Raspberry Pi systems.
ii linux-raspi2-hwe-18.04 5.3.0.1017.6
arm64 Complete Linux kernel for Raspberry Pi systems.
After the upgrade is complete this is the only kernel meta installed:
ii linux-image-raspi 5.4.0.1015.50
arm64 Raspberry Pi Linux kernel image
During the upgrade, these kernel packages update are made:

At the end of the upgrade process, do-release-upgrade calculates the obsolete
packages and remove the following kernel packages:
linux-headers-5.3.0-1017-raspi2
linux-headers-5.3.0-1030-raspi2 linux-headers-5.4.0-1015-raspi
linux-headers-raspi linux-headers-raspi2-hwe-18.04
linux-image-5.3.0-1017-raspi2 linux-image-raspi2-hwe-18.04
linux-modules-5.3.0-1017-raspi2 linux-raspi
linux-raspi-headers-5.4.0-1015 linux-raspi2-5.3-headers-5.3.0-1017
linux-raspi2-5.3-headers-5.3.0-1030 linux-raspi2-hwe-18.04
Please note that the flavour of the raspberry pi kernel changed from
"raspi2" on 18.04 to "raspi" on 20.04. The transitional packages in
20.04 seem to be correct, so this behaviour is likely an issue with do-
release-upgrade not handling this rename correctly and removing too many
packages.
