Hi,

please downloading latest jomsocial package at jomsocial.com > my account
unzip that package, and you will find newest ijoomla installer. install it and try to upgrade jomsocial again.

if still cant, for temporary you can use conventional way from joomla backend > manage. and upload newest jomsocial package.

FYI:
I will assign this topic to ijoomla developer, just in case if the issue still happening after upgraded.

Regards
