  • Don't this is a terrible idea, python3 is a dependency for so much (I think even apt is a dependency) edit: Gah someone beat me to it – j-money Jan 25 '19 at 13:58

    Removing Python 3 will destroy the operational state of your system because so many things depend on it. *DO NOT* remove Python 3 from your system. Instead, address the actual errors you're seeing, rather than assume that Python 3 being present is the cause. – Thomas Ward Jan 25 '19 at 14:32

Ubuntu 16.04 comes with Python3 installed by default. If you want to install Python 2 you can run:

sudo apt install python-minimal

On the command line you should use python3 or python2 to execute scripts.

Also take note that ubuntu-desktop is a package that will install a full display system such as X server and Gnome packages, none of which you'll have much use for if connecting over SSH.

However, the problem you may have now is that you've attempted (or succeeded to some degree) in removing Python, which is actually what the package management tool apt uses to install/remove packages.

  • Doesn't 16.04 come with Python 2 installed? I thought 17.10 was the first release not to. – wjandrea Jan 25 '19 at 14:38

    I thought so too, but I actually fired up 16.04.5 in a VM and it's not there by default at least with a server installation, only python3 was. – Kristopher Ives Jan 25 '19 at 15:26
  • I accidentally uninstalled python3 on ubuntu 20.04. The system wouldn't boot successfully, giving "/dev/sda2: clean **/** files **/** blocks". Installing python3-minimal and ubuntu-desktop saved me from unemployment. LOL – Adam Beleko Jan 03 '22 at 18:46

This seems like an XY-problem. Problem Y, uninstalling Python 3, will break your OS. Don't do that.

Problem X is not clear, but assuming it's that the system Python 3 executable is damaged, you can reinstall it via the package python3.5-minimal:

sudo apt-get install --reinstall python3.5-minimal
