Encountered this issue, the base folder for the plugin wasn't created in the corresponding files directory, and the upload function only tried to create a subfolder of the plugin space.

The install/uninstall hook should include the folder creation/removal:

The GLPI installation already ask for administrator to get write access on its files directory; just use GLPI_PLUGIN_DOC_DIR/{plugin_name} (that would resolve to glpi_dir/files/_plugins/{plugin_name} in default basic installations). Make sure to create the plugin directory at install time, and to remove it on uninstall.
