I have created my own repository for QGIS. If I now install my plugin from this repository, I get the following error message:
Plugin has disappeared: The plugin seems to have been installed but I don't know where. Probably the plugin package contained a wrong named directory. Please search the list of installed plugins. I'm nearly sure you'll find the plugin there, but I just can't determine which of them it is. It also means that I won't be able to determine if this plugin is installed and inform you about available updates. However the plugin may work. Please contact the plugin author and submit this issue.
When I restart QGIS and activate the plugin, it works without problems.
My repository looks like this:
<plugins> <pyqgis_plugin name="Name" version="0.1"> <description>xxx</description> <homepage>www.xxx.com</homepage> <qgis_minimum_version>3.0</qgis_minimum_version> <file_name>plugin.zip</file_name> <author_name>Name</author_name> <download_url>http://xxx.com/plugin.zip</download_url> </pyqgis_plugin> </plugins>
