I have read the following thread which is about the same question that I have. In its fourth post marked as the solution of this thread, @Aragorn wrote:
It seems to me to not completely answer the question of @RubenStobbart in this cited thread, since the 5.4 is for example now marked as LTS but not marked as recommended in my graphical kernel manager. So being marked as LTS or as recommended seems to be 2 different things.
Why is the LTS kernel 5.4 not marked as recommended? When will be then the 5.4 kernel marked as recommended in this graphical kernel manager?
Thanks in advance for your help!
