I tried to update ISPConfig 3 last night asking the web interface to do the job. I found this morning that the interface wasn't working, although the sites were working (i think that the cron jobs crashed). So I tried to update using the shell. When I type ispconfig_update.sh a copy of ISPConfig 3 is downloaded, a lot of files decompressed but the installation crashes saying:
Operating System: Debian 6.0 (Squeeze/Sid) or compatible
PHP Notice: Undefined variable: conf in /tmp/ispconfig3_install/install/update.php on line 76
If I try to update using php -q update.php I receive the same error. I tried to uninstall it but nothing happens.
