Graphical bash does not run after removing python [duplicate]
Solution 1:
Ubuntu relies heavily on python, so by removing python the tools that require it to function need to also be removed.
The tools also are built for a specific version of python, so if that version isn't available, you'll find they may no longer run (tools such as gnome-terminal requires the python it was built for; what came with your release; that was what it was tested to run with; if your system doesn't have that version - it may not run, or may not run correctly).
