Upgrade – 16.04 LTS Upgrade Alert: How to Handle It

14.0416.04upgrade

I am running Ubuntu 14.04 LTS. Today when I logged into my computer I got an update alert saying that I could upgrade to Ubuntu 16.04 LTS. The other options were not now or do not upgrade. If I chose to upgrade will it delete my /home directories and the installed software under /opt and /usr/local ?

The upgrade will not delete your files and installed software.

It will upgrade all software installed from Ubuntu repositories to new versions.

Please take in account that an upgrade can fail. There is no 100% guarantee it is successful.

If you are not sure, select "not now".

Ubuntu – How to upgrade from Ubuntu 14.04 to Xubuntu 16.04

I don't think you can update from Ubuntu to Xubuntu. But you can simply sudo apt install xubuntu-desktop to get everything that xubuntu would install.

About your upgrade: (X)Ubuntu 16.04 isn't released yet. You could force the update on the dev version by running sudo do-release-upgrade -d.

But since you had to ask that, I would recommend holding off another couple of weeks until it's stable. (and then maybe another couple of weeks while the early adopter update :-))

Ubuntu – Kernel did not upgrade between 14.04 LTS to 16.04 LTS

This happens sometimes for some reason.

It can be easily fixed in 16.04 by

sudo apt install linux-generic

This will install the correct kernel and the meta package for kernel upgrades.
