 ## Overview
 
 The `apt` (Advanced Package Tool) command on Ubuntu is a powerful tool that's used for package management. It enables you to install, remove, update, and manage software packages on the Ubuntu system. You can use `apt` to search for available packages, install specific versions of packages, and handle dependencies efficiently. It simplifies the process of software management by providing a command-line interface to interact with the APT libraries.

+### Cause: Permission issues affecting the keys under `/etc/apt/trusted.gpg.d ` can be seen when running apt with debug flags
+
+```bash
+$ sudo apt update -oDebug::Acquire::gpgv=1
+...
+...
+http://azure.archive.ubuntu.com/ubuntu/dists/jammy/InRelease: The key(s) in the keyring /etc/apt/trusted.gpg.d/ubuntu-archive-2018.gpg are ignored as the file is not readable by user '_apt' executing apt-key.

+...
+...
+```
+
+#### Solution: Correct permissions to be 644 for the key files under `/etc/apt/trusted.gpg.d` and also check the default umask for your installation
+
+1) Correct permission for the keyring files
+```bash
+$ sudo chown 644 /etc/apt/trusted.gpg.d/*.gpg
+```
+
+2) Check the default umask set by running
+```bash
+$ sudo umask
+```
+
+The default umask for most distros is usually set under `/etc/login.defs` and it is set to 0022. There have been cases where the umask was being set to 0777 which results in null permissions for created files.
