Title:
the dependency of kernel package should restrict expected version of
linux-firmware
Status in linux package in Ubuntu:
Triaged
Bug description:
Recently, we got a lesson learn from oem issues[1][2] that linux-
firmware should always be updated while update kernel package.
The root cause is some kernel update will expect linux-firmware be updated as
well.
Users who install new kernel manually could also encounter the same issue
that expected firmware is not there to feed new installed kernel.
There's a dependency for linux-firmware in linux-image-generic but not
restrict the version.
That means installing new kernel manually will not pull latest linux-firmware
as well.
Say, in [2] case, user's system have:
linux-firmware 1.157.4
linux-image 4.4.0-73
Then user install newer kernel by apt-get install, and he will
encounter the same error because the newer linux-firmware will not be
installed as well.
So for better user experience, the depends of each released linux-image
packages should be changed to something like
Depends: linux-firmware (>= 1.157.17)
or to make sure kernel could backward compatible if kernel package not
restrict it's linux-firmware dependency.
