** Description changed: 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.
