Installing Magisk modules can sometimes be frustrating, especially when encountering unzipping errors. While the Magisk developer guide states that the META-INF folder is only needed for flashing in recovery, this information is outdated.

In reality, the META-INF folder is required for *all* Magisk module installations, including those performed through the Magisk app. Without it, Magisk will be unable to properly identify and install the module, leading to the dreaded unzip error.

This error impacts users across various devices and Android versions. For instance, users on Magisk v28.1 have reported this issue. Therefore, it's crucial for module developers to include the META-INF folder in all modules, regardless of the intended installation method.
