upgrade - How did I end up with 16.04 LTS but 2.6.32 kernel, and how to fix it? - Ask Ubuntu


for reason, vps seems running ubuntu 16.04.1 2.6.32 kernel. how possibly have ended here, given 16.04.1 comes 4.4 kernel? , how can safely fix problem?

i tried apt install linux-generic (and rebooting afterwards) didn't help.

diagnostic info

when log on vps, get:

welcome ubuntu 16.04.1 lts (gnu/linux 2.6.32-042stab117.14 x86_64)

relevant command output:

$ lsb_release -r release:    16.04 $ uname -r 2.6.32-042stab117.14

2.6.32-042stab117.14 kernel number virtuozzo (openvz).

openvz container-based virtualization linux. openvz creates multiple secure, isolated linux containers (otherwise known ves or vpss) on single physical server enabling better server utilization , ensuring applications not conflict. each container performs , executes stand-alone server; container can rebooted independently , have root access, users, ip addresses, memory, processes, files, applications, system libraries , configuration files.

openvz free open source software, available under gnu gpl.

and include ubuntu container.

the version numbering explained here:

new-style versioning

currently (since 2.6.20) new openvz kernels has simple version 2.6.n-ovzxxx

  • 2.6.n vanilla kernel version, e.g. 2.6.20 or 2.6.22, openvz kernel based on;
  • ovzxxx openvz kernel version, e.g. ovz001 first one.

old-style versioning

some time ago openvz kernel versions named 2.6.n-xxxtestyyy.z , 2.6.n-xxxstabyyy.z.

  • 2.6.n vanilla kernel version (i.e. 1 kernel.org) openvz kernel based on.
  • xxx major openvz kernel version number, changes release release, or when dramatic changes kernel made.
  • test series kernels unstable kernel releases, under extensive development, while stab series kernels more or less stable kernel releases close released or in production already.
  • yyy minor openvz kernel version number, changes build build, when bugfixes or small feature changes made.
  • z add-on number; used rpm's release field , in cases set 1.

this style kept kernels started before switching new versioning.
