[Koha] Plugin Error

[SATISH]

Hello Paul,

I am trying  again for Koha Plugins now, unfortunately not successful with
Koha 18.11 on Debian 9.11 (Stretch),

# chown gechlibrary-koha.gechlibrary-koha
/var/lib/koha/gechlibrary/plugins/

I tried chown with 3 users # ps -ef  | grep apache

1) gechlibrary-koha
2) www-data
3) root

I am getting the error.
i,e., *Cannot unpack file to the plugins directory. **Please verify that
the Apache user can write to the plugins directory*

Not sure, how to make Plugins working. Kindly suggest any other alternative
ways.

With Thanks
Satish MV
