Drop sudo in your script, there is point to use it if you're running as root. This is also the reason that DEBIAN_FRONTEND has no effect - sudo drops your current user's environment for security reasons, you'd have to use with -E option to make it work.

Looks like this is part of an actively tracked issue with Tkinter in PyCharm. You can find the reference on the Pycharm's developer's issue tracker. The issue is undiagnosed, but if looking at similar problems with Tk on StackOverflow, one can see that it's an issue with thread safety and/or multithreading.

All I can do is speculate as to the cause, which is not helpful, however, I can at least collate the suggested workarounds:

1. Switch to a different Matplotlib backend (See docs: What is a backend?). Such as Qt5, but you will need to make sure they are available in your environment.

   This approach is the most promising as other backends are better able to deal with not being the main thread or are explicitly safe for multi-threading. It's also the simplest unless you have a really specific reason for preferring TkAgg.

2. Do not use the debugger with interactive plots.

3. Set "Variables Loading Policy" to "Synchronously" in Debugger as suggested by a PyCharm dev in the linked issue.

4. Enable "Scientific mode" in Pycharm.

5. More esoteric workarounds such as closing your figures within the code before drawing the second one. Example, after plotting the first figure:

The error occurred because you have installed your dependencies using Sudo. This has installed your pip dependencies only for Sudo users, whilst you are running your Django application as a non-sudo user. This is the reason why you didn't saw your packages when you did pip freeze but you saw them after doing sudo pip3 freeze

To solve this

1. Install python3-venv with this command sudo apt-get install python3-venv
2. Create a virtual environment python3 -m venv env this command will create a virtual environment named env
3. Activate the virtual environment with this command source env/bin/activate

Once you have done this you will see a (env) before your shell which indicates that your virtual environment is activated now need to install the dependencies inside this

1. cd to your requirements.txt and type pip3 install -r requirements.txt make sure you do it without sudo (because you will run your Django app in your web server as a non-sudo privilege user for security reasons)

After this, you can run your Django app with your virtual environment kept active.

Highly doubt that anyone would have the same scenario, but I solved it by just using a separate docker container for memcached and connecting my application to that instead.

Maybe your port 5000 is already occupied by some other process. Try netstat

mysql user is looking for a home directory, which seems to have not been assigned. To do that, you can execute:

you have :

I think you should try these advices Basic Flask app not running (TypeError: required field "type_ignores" missing from Module)

If it does not help please provide output from

The 'Allowed origins are' line specifies that Debian and Debian-Security are allowed to be upgraded from.

In the output of apt-cache policy ca-certificates you can see that ca-certificates comes from a different source, buster-updates.

To alter this you can uncomment the "origin=Debian,codename=${distro_codename}-updates"; line in /etc/apt/apt.conf.d/50unattended-upgrades or override the Unattended-Upgrade::Origins-Pattern config in a later file.
