I have an Ubuntu LTS 16.04.02 with an 4.4.x Kernel from March. When I try to update the system it claims to be uptodate. This is not true. So why do not get the updates?
root@p1sr1:~# uname -a
Linux p1sr1 4.4.0-66-generic #87-Ubuntu SMP Fri Mar 3 15:27:09 UTC 2017 i686 i686 i686 GNU/Linux

Edit: after some further information via the comments, it seems that the source.list seems to be not ok on my system. Does anyone have a default sourcelist for LTS 16.04.2, I like to compare with my system.
Edit II After getting the correct source.lists I could now update to Kernel 4.10 but I am still on LTS 16.04.2 !! I tried to do an dist-upgrade but this comes back with 0 packages to update... So I am in a much better state now but the initial question: How can I upgrade from LTS 16.04.2 to LTS 16.04.3 is still on my desk. Any hint is highly well come!
