I'm running Ubuntu 18.04.3 on a Dell XPS13. When I did the upgrade from 18.04.2 to 18.04.3, I was led to believe system would be running a Linux 5 kernal. It appears that I'm still running a Linux 4 Kernel:
david@david-XPS-M1330:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.3 LTS
Release: 18.04
Codename: bionic
david@david-XPS-M1330:~$ uname -a
Linux david-XPS-M1330 4.15.0-58-generic #64-Ubuntu SMP Tue Aug 6 11:12:41 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
Any idea's how I've screwed this up? I did a similar upgrade on Ubuntu MATE and that is running Linux 5. Any suggestions would be appreciated
