I just upgraded from Ubuntu 15.04 64-bit to Ubuntu 15.10 64-bit. I read that 15.10 was using the 4.1 or 4.2 kernel, but I noticed that my kernel didn't upgrade.

When I type in the terminal uname -r, I get 3.19.0-18-generic

Same thing in GRUB: the only kernel I can choose is 3.19.0-18

Can someone explain how to upgrade the kernel?

This is a bug in the distribution upgrade script.

You can install the correct kernel by running:

sudo apt-get install linux-generic

After a reboot you should have the 4.2 kernel.

There are two bugs here, one in software-properties https://bugs.launchpad.net/ubuntu/+source/software-properties/+bug/1506169 and one in the ubuntu upgrade process https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1509305. Both of these are being fixed and should be resolved shortly.

As mentioned installing linux-generic before or after the upgrade will ensure you have the new version of the kernel installed.

The version of release upgrader in -proposed will now (2015-10-28) do the right thing, you can use it via adding the "--proposed" switch to do-release-upgrade or check-new-release-gtk. Alternatively, if you wait a couple of hours the fix will move to updates and will just work.
