I am having the same problem upgrading from 3.4.33 to 3.4.36. Space is not an issue. Can you please tell me how to update manually? I downloaded the jevents34_3.4.36.zip file and copied the contents to a new folder, then uploaded that folder to the server. I then went to Install from Folder in Joomla and entered the path to that folder, but get this error:
Warning
JFolder::create: Could not create folder.Path: /var/www/html/tmpj3ew7/jevents/install_5904c9b89d2cf
Install path does not exist.
Package Update: There was an error installing an extension: com_jevents.zip
Error
Unable to create destination
Error installing package
