Upgrading to Ubuntu 24.04 LTS may cause problems with Docker Desktop. Follow these steps to resolve them quickly.

Prerequisites

1. Internet connection.
2. Docker CLI installed (Guide here).
3. GPG key setup (optional for Docker login).

Step 1: Verify Docker CLI

1. Run the following command in your terminal to verify Docker is working:

   sudo docker run hello-world

1. If successful, proceed to install Docker Desktop.

Step 2: Install Docker Desktop

1. Download Docker Desktop from here.
2. Run these commands to install:

   sudo apt-get update
   sudo apt-get install ./docker-desktop-<arch>.deb

(Replace <arch> with your system architecture, e.g., amd64.)

Step 3: Fix Permission Issues

If Docker Desktop doesn’t open, fix the permissions by running:

echo 'kernel.apparmor_restrict_unprivileged_userns = 0' | sudo tee /etc/sysctl.d/20-apparmor-donotrestrict.conf

Then restart your system:

sudo reboot

Step 4: Set Up GPG Key (If Login Issues)

1. Install password manager:

   sudo apt-get install pass

1. Generate a GPG key:

   gpg --generate-key

1. Initialize pass:

   pass init "your_email@example.com"

Step 5: Restart Docker Desktop

Log in with your Docker ID, and you’re all set! ✅
