How do I reinstall Ubuntu from the terminal? - Michelle M (2023)

Reinstalling Ubuntu via Terminal can be done in several ways, depending on which version of Ubuntu you have installed and how you want to reinstall it.

First, if you just want to do a fresh install of the same Ubuntu version, the easiest way is to use the built-in reboot option. You can open a terminal window by pressing CTRL + ALT + T and typing "sudo apt-get install -f".

This will reinstall all necessary files and reset all settings.

If you want to install a different version of Ubuntu, you'll need to use a different method. In that case, the easiest way is to use a pendrive or a CD/DVD with the installation files.

After the installation is complete, you can log in as usual and you will be running the new version of Ubuntu. You must make sure that you download any necessary software or application and configure its settings as you wish.

If you already have an Ubuntu ISO image file, as an alternative to a USB stick or CD, you can use "Boot Creator" to burn this image directly from the terminal onto a USB drive. To do this, open a terminal window and type "sudo apt-get install usb-creator-gtk".

This will open a window where you can burn the ISO image to the USB drive.

Once this is done, the USB drive can be used in the same way as the memory stick or CD mentioned above. This can be a useful way to reinstall Ubuntu without the need for an external drive.
