ispconfig upgrade script from 3.0.4.6 to 3.0.5.2 fails the to upgrade

Is there any way i can install the new version of Ispconfig without breaking anything? i just cant upgrade. it fails every time i try.

 

Hi,

I'm still unable to upgrade. Still bomb out after backups. Have followed everything here to date and still nothing...
Looks like this is going to be the last version running on this production server.

>> Update

Operating System: 12.10 (Quantal Quetzal)

This application will update ISPConfig 3 on your server.

Shall the script create a ISPConfig backup in /var/backup/ now? (yes,no) [yes]:

Creating backup of "/usr/local/ispconfig" directory...
Creating backup of "/etc" directory...
admin@server1:/var/www/#

i still have the same problem not able to upgrade.
