Ubuntu – How to completely remove and reinstall Ubuntu

deleteinstallation

I want to reinstall Ubuntu, but I also want all information and settings to disappear. So everything looks like the first time I installed it. Is it possible to do so via Terminal? Or what are the steps I should follow?

Best Answer

You cannot perform a reinstallation of Ubuntu from an existing installation.

Use Ubuntu live disk to boot up.
Select Install Ubuntu on hard disk.
Keep on following the wizard.
Select the Erase Ubuntu and reinstall option (the third option in the image).

On #1, to get a list:

To reinstall the list on a new installation:

sudo dpkg --set-selections < software_list
sudo dselect

On #2, you need to know where configuration files are located. (Backup the files in /etc and your home directory at least).

On #3, yes it is possible. Yet, later you could find out how to install a missing application, though another repository, possibly.

Running these commands should fix your problem:

sudo apt-get update
sudo apt-get --purge reinstall oracle-java7-installer
sudo apt-get upgrade

If they do not, then please edit your question to include all the text from the Terminal from when you ran them (as the output would still be diagnostically useful).
