  • Version :Ubuntu 16.04.3 LTS
  • Kernel version : 4.12.0-041200-lowtency

How can I roll back to the default (original) and correct kernel for my Ubuntu version? I installed a newer kernel and deleted all the other kernels from /boot. I installed the new kernel manually and without installing HWE.

When I run sudo apt update && sudo apt full upgrade, it doesn't download any kernels, just the usual sources.list file check and finally it says (0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded`.

How can I install the default Ubuntu kernel for my system?

    did you delete all the other kernels? have you made changes to APT? How did you install the 4.12 kernel – Zanna Aug 27 '17 at 12:59

    Yes i did it to free some space to my /boot – Abdalrhman Rafik Aug 27 '17 at 13:01
  • If you run sudo apt update && sudo apt full-upgrade, does it install any kernels? Please could you [edit] your question to add more information? – Zanna Aug 27 '17 at 13:06
  • OK, thanks for the update. Could you please try to install the current 16.04 kernel explicitly using the command sudo apt install linux-image-4.4.0-92-generic. Could you also tell us how you deleted the other kernels you had installed? – Zanna Aug 27 '17 at 13:34

I fixed this by installing the current 16.04 kernel explicitly with the command 

sudo apt install linux-image-4.4.0-92-generic
