Change Ubuntu 17.04 to Ubuntu 16.04.2 LTS [duplicate]

I've upgraded my LTS version of Ubuntu to Ubuntu 17.04 and from the day I've upgraded I've been struggling to get this thing stable. Sometimes my Wifi adapter doesn't work properly and sometimes I can't even copy things properly.

So I want to revert back to Ubuntu 16.04 LTS.

Is there any way to get this done?

Solution 1:

The best way is to re-install Ubuntu, so that you have a clean installation, without conflicts.

You need to have an installation CD/DVD/USB of Ubuntu 16.04.2 LTS.

• Then backup your relevant files, just copy them to an external drive or a secondary partition.
• Then run the installation CD/DVD/USB.
• On the installation select "Erase Ubuntu xx.xx and reinstall"
