Hi farhad, and welcome to Kubuntu Forums!

The terminal instructions to do a distribution upgrade are on the first post of this thread: https://www.kubuntuforums.net/showth...ght=do-release

sudo apt-get update
sudo apt-get dist-upgrade
sudo do-release-upgrade -d

But, if you read the whole of that thread you might want to re-think doing this. Many of us here think you'd be better off sticking with K14.04 for some time as there are still a lot of problems with the change to Plasma5 in K16.04. I'm sticking with K14.04 as too many things in the new Plasma5 aren't working as well as I'd want for a stable and configurable system. I agree with oshunluvr's post #2 on that thread myself.

You don't need the downloaded ISO of Kubuntu 16.04 to upgrade using the above instructions as the system will download all needed packages separately. Make sure you back up everything important to you prior to doing the distribution upgrade (things can go wrong).

ya ,,,,,you do not nead the -d option on that

sudo do-release-upgrade -d

as it's not a dev release but a full release now .........

and I would not do it from 14.04 anyway , you will be going to plasma5 from plasma4 and the potential for quirks will be high .

a clean install with a new /home/you would be best if you must upgrade.

However their is nothing wrong with keeping 14.04 ,,,,,,,,,I still have it as well ,,,,,,,and a few more

Good catch Vinny! I've never actually done an upgrade this way myself so I missed that option wasn't needed. I've always done clean install upgrades till now.

thank you both.
i finally decided to install a fresh 16.04 on my system.
