I just upgraded my Ubuntu 14.06 to 18.04. At the boot screen, I press ESC
and choose the Advanced options for Ubuntu
. And I see 2 items:
- Ubuntu, with Linux 4.15.0-33-generic
- Ubuntu, with Linux 4.8.0-36-generic
Why there are 2 of Linux versions?

Older working kernels are automatically retained to help you recover in case of several types of possible kernel failure or incompatibility.
Ubuntu typically retains one older kernel, which rotates as new kernels are installed.
