Step by step guide

The installation of Cura using the package manager is fairly easy. In the following steps, I will explain how to get it done.

Method 1: Using ppa-purge

  1. Take a terminal like Konsole or any other, which is installed on your computer. Most of the terminals look the same but differ only in their usage. However, since we are using only the basic functionality, it won’t matter which one we take. After opening the terminal, you should be able to see something like this
  2. Type in
    sudo ppa-purge ppa:thopiekar/cura
    

    and follow the instructions in the terminal. This command will remove the Cura PPA from the list of repositories of your package manager and remove all packages, which have been installed from there before. To uninstall the master PPA the command

    sudo ppa-purge ppa:thopiekar/cura-master

    is needed instead.

  3. Since Ubuntu 18.04 (Bionic Beaver) Cura is also available in the software repositories of Ubuntu. You will need to execute “sudo apt remove cura” to uninstall Cura completely.
  4. Now you successfully uninstalled Cura!

Method 2: Using synaptic

Using Synaptic you can easily see where your installed packages are from. In our case, you can easily select the PPA and remove all packages from there. For more info on using Synaptic search the web for manuals. There are enough around…

Method 3: Apt-Pinning

An easy method for advanced users is to change the PPAs priority using APT pinning. While choosing a low “Pin-Priority” you can even tell APT to avoid a repository, if needed. Using a low here will tell APT to downgrade to the Ubuntu packages
