+
+## Common Issues
+
+### Couldn't create symlink
+
+If you encounter the following error message when packing with `cpack -G DEB`:
+
+```bash
+NEXO Engine symlink couldn't be created. Required for the DEB package generator. See README's troubleshooting section.
+```
+
+To create an installer using the cpack DEB generator, our scripts try to create
+a symlink to NEXO's binary. This symlink is
+required for installing NEXO in the path of a DEB compatible linux distribution.
+
+#### Solution
+
+If you are running Windows:
+- Either ignore this message, since you may not want to generate a DEB package.
+- If you still want to generate a DEB package, you should enable Windows Developer Mode,
+  see [Microsoft Documentation](https://learn.microsoft.com/en-us/windows/apps/get-started/enable-your-device-for-development).
+  And rerun the cmake configure, build and cpack commands.
+
+> [!WARNING]
+> If you are running Windows, you may not want to generate a DEB package. It may not be supported.
+
+If you are running another OS, it is unexpected, so please submit an issue [here](https://github.com/NexoEngine/game-engine/issues)
+with the details of your OS and the error message; we will help you from there.
+
+### CPackDeb: file utility is not available
+
+If you encounter the following error message when packing with `cpack -G DEB`:
+
+```bash
+CPackDeb: file utility is not available.  CPACK_DEBIAN_PACKAGE_SHLIBDEPS
+  and CPACK_DEBIAN_PACKAGE_GENERATE_SHLIBS options are not available.
+```
+
+The DEB generator couldn't find the `file` command.
+
+#### Solution
+
+You need to install the `file` command on your system. 
+
+On Ubuntu/Debian, you can install it with the following command:
+
+```bash
+sudo apt update && sudo apt install file
+```
+
+On Windows (using chocolatey), you can install it with the following command on an elevated PowerShell:
+
+```bash
+choco install file
+```
+
+> [!WARNING]
+> If you are running Windows, you may not want to generate a DEB package. It may not be supported.
+
+### CMake configure/build infinite loop
+
+If you encounter an infinite loop when running the `cmake` command, it may be due to various reasons.
+
+#### Solution
+
+- Check if date and time are set correctly on your system.
+- Something is modifying cmake files after each run. Check if you have any scripts or tools that modify the CMake files.
+- Try to delete the `build` (might be another name) directory and rerun the `cmake` command.
+
