I’m facing challenges in disabling AppArmor on my Ubuntu 20.04 LTS system. Can anyone provide guidance or solutions on how to effectively turn it off?

I’m running into a bit of a snag with my Ubuntu 20.04 LTS setup, and I’m hoping someone here can lend me a hand. So, here’s the deal: I’ve been trying to disable AppArmor because it’s causing some issues with the application I’m working on. I thought it would be a straightforward process, but it’s turned out to be a bit more complicated than I anticipated.

I’ve looked up some guides online, and they mostly mention using the command line, but to be honest, I’m not the most comfortable with terminal commands. I get that I probably need to run a few commands to stop AppArmor, but I’m a little nervous about messing something up. I definitely don’t want to break anything on my system, especially since I use it for my projects and other important stuff.

I’ve tried a couple of commands I found in those tutorials, like `sudo systemctl stop apparmor` and `sudo systemctl disable apparmor`, but honestly, I’m not sure if that’s all I need to do. I feel like there should be a more thorough way to ensure it’s completely turned off. Plus, there are so many mentions of AppArmor profiles, and I really have no idea how they fit into the picture.

Also, I’ve read that disabling it can potentially open up some security risks, so that’s got me wondering if it’s worth it or if I should find a way around whatever issues I’m facing with the app instead. Is there anyone who has dealt with this before? What steps did you take to safely disable AppArmor? Or, if you have any alternative suggestions for getting around the issues without turning it off, I’m all ears.

Honestly, I’d appreciate any advice, even if it’s just a simple recap of the exact commands you used. If you could throw in some tips or point me towards a good resource that breaks down the process for people like me who aren’t terminal experts, that would be amazing. Thanks in advance!

    1. It sounds like you’re dealing with a frustrating situation! Disabling AppArmor can definitely feel a bit daunting, especially if you’re not super comfortable with the terminal.

      First off, the commands you mentioned are definitely the right steps to take. Here’s a quick recap:

      • sudo systemctl stop apparmor – This will stop the AppArmor service temporarily.
      • sudo systemctl disable apparmor – This command will prevent AppArmor from starting at boot time.

      But if you really want to ensure that it’s completely turned off, you might want to check that it’s not running anymore after you stop it. You can use:

      sudo systemctl status apparmor

      It should tell you if it’s inactive now. If it still shows as active, you might need to reboot your system to see the changes take effect.

      About AppArmor profiles, they are basically rules that tell your system how to restrict applications. If you’re looking for a more secure way to run your app without completely disabling AppArmor, you could consider adjusting the specific profile for your application instead of turning it off. This would allow AppArmor to continue protecting your system while your app runs smoothly.

      As for security risks, it’s true that disabling AppArmor can leave your system a bit more exposed, but if you’re in a development environment (and not running critical services), it might be fine temporarily. Just weigh the risks based on what you’re working on.

      If you’re looking for more info or help, I’d recommend checking the Ubuntu forums or Ask Ubuntu. There are a ton of friendly folks who are more than happy to help out. And when in doubt, don’t hesitate to ask specific questions there!

      Good luck! You got this!


    2. To safely disable AppArmor on your Ubuntu 20.04 LTS system, you can follow these steps. Firstly, you correctly started with the commands you found: sudo systemctl stop apparmor stops the AppArmor service, and sudo systemctl disable apparmor prevents it from starting at boot time. To confirm that AppArmor is indeed inactive, you can check its status with sudo systemctl status apparmor. If you see that it’s inactive, you can be assured that it has been successfully disabled. However, if you want complete assurance, you might also want to remove the AppArmor profiles associated with your application, which can be found in the directory /etc/apparmor.d. Be cautious while editing or removing these files, as they could affect other applications relying on AppArmor.

      While disabling AppArmor might resolve your immediate issues, as you mentioned, it does come with some security risks. Instead of permanently disabling it, consider putting the specific application into complain mode using sudo aa-complain /path/to/your/application. This will allow the application to run with fewer restrictions, logging any potential security violations instead of blocking them. This way, you can still benefit from AppArmor’s protection for other applications while troubleshooting your specific issue. If you’d like more detailed guidance, you could look into resources like the official Ubuntu documentation or community forums which offer step-by-step instructions tailored for less experienced users.
