How do I switch from Ubuntu 16.10 to Ubuntu 16.04?

Question

I've accidentally installed Ubuntu from a 16.10 iso image instead of 16.04 and I do not want to reinstall it via a format...

Is there a way I can downgrade from 16.10 to 16.04?

PS:

I desire to have an LTS release as to guarantee a certain stability level, would downgrading to 16.04 be a waste of time since 16.10 would allow me such stability, or switching to 16.04 is the logical thing to do?

Solution

There is no way to downgrade. You can install 16.04 from scratch.

16.10 has not been released yet, and you can't expect stability from a development version.

Please also take in accont that questions about Ubuntu 16.10 are off-topic at this site till the end of October, when it is planned to be released.

Thank you for your quick answer. How do I go about this question as it is off-topic? should a deletion take place?

My opinion is that this question is on topic, because it is about installation of 16.04. But other questions regarding unreleased versions are off topic.

well you can just download older kernel ..and use 16.10 for purpose for what still 16.10 is not supported,like amd-gpu-pro with vulkan,etc...yeah there are so many answers to your question,because GNU/Linux means freedom of many choices, and yes depends why you want to do it!

For me there is no file etc/apt/preferences instead, I have a dir etc/apt/preferences.d and it's empty with 0 items even hidden. Instead of a downgrade, I'm trying to move my 16.10 from my main machine to another machine 16.04. If that goes well, I will repeat on my main machine. So far 5 attempts all got broken. Either unity won't start on boot, or login into a blank screen.
