I'm getting an error, too, while trying to update from 3.4.29 to 3.4.30 on Joomla 3.6.5.
Since my last JEvents update I've migrated my website to a new host and initiated SSL for my entire site.
I also tried to install JEvents 3.3.30, and received another error. I've attached images of both.
Either, or both, of these actions could be a cause. Does anyone have any advice?
The full error string is...
Warning
JFolder::create: Could not create folder.Path: /home1
