Describe the bug
Unable to install the plugin on QGIS 3.10

To Reproduce
Steps to reproduce the behavior:

1. Install QGIS 3.10 and open the software (I would not advise to install 3.10 if 3.4 is already present on your system)
2. Search for the GeoSYS plugin
3. Install it
4. See error:

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.

Expected behavior
We should be able to install the plugin.
