Install of upgrade from 3.02 to 3.0.4. fails

[ptrouw]

Unclear why, ends with a 404. With debug on and error message maximum, the following message shows:

Error log on server:
[Sat Jan 31 11:02:07 2015] [warn] [client] mod_fcgid: read data timeout in 40 seconds, referer: http://xyz.com/administrator/index.php?option=com_installer

I did a FTP copy, I only don't know if it needs a database upgrade as well?

The AIO fails as well!

all points to a timeout issue on your mod_fcgid - consult your host
