Upgrade issue from Debian Server Squeeze 6 to Wheezy 7 – still on kernel 2.6

Christos Baziotis asked:

I upgraded from Debian Squeeze 6 to Wheezy 7 but it seems i am using the old kernel.

# uname -r

But i have the newer kernel installed

# dpkg --get-selections | grep linux-image
linux-image-2.6-amd64                           install
linux-image-3.2.0-4-amd64                       install
linux-image-amd64                               install

What should i do?

Here is the proccess i followed to upgrade:

apt-get update
apt-get upgrade
apt-get dist-upgrade
apt-get autoremove


echo '' > /etc/apt/sources.list

cat <<EOF >> /etc/apt/sources.list

apt-get update

apt-get install linux-image-2.6-amd64


My answer:

You’re on an OpenVZ (container) based virtual machine. As a result you have no control over the kernel; it is provided by your hosting provider, and you are limited to whatever the provider chooses to provide.

If you want a different kernel, you either need to contact your hosting provider, or use something other than OpenVZ.
