Upgrading the kernel
uname -r 126.96.36.199-x86_64-linode1
I didn't realize I was behind until I looked at available kernels.
How do I upgrade?
To update the kernel, update it normally with apt-get, yum, or whatever else your distro uses, and make sure your grub menu list has the right kernel as default.
As a warning, though, you shouldn't be using a custom kernel unless you have a specific need to do so.
Do you know what kind issues I might face if I were to boot with the linux kernel now that I have been using the distro kernel?
