Can't proceed the upgrade to version 3.0.3.3

[yoplait]

I can't upgrade my ispconfig this time ...

I can download the file from my computer, with firefox, but wget, from the server, seems to do not want this link... Is there something i did wrong ?

(I used ispconfig_update.sh, with root and the server has just passed from Debian lenny to squeeze.

# ispconfig_update.sh

Here are some news ... :
I decided to reboot the server, because some things went wrong.
After the reboot, the problems seems solved, but I always have a problem with ispconfig :

The begin is the same as the first quoted message, except for the end, that says :

Select update method (stable,svn) [stable]: stable

Unable to retrieve version file.

I'm pretty sure to do not have deleted any file in ispconfig configuration... Where must it be ?

Thanks for your help.

You have problems with dns resolution on your server and for that reason, the ispconfig update fails. Make sure that the dns servers in the file /etc/resolv.conf are working and rechable from your server.
