I tried to upgrade an ispconfig multi server config from 3.2.2. to 3.2.3 and got the following error message (or lets say, part of a message): Do you want to rename these conf-custom templates now so the default templates are used? (yes,no) [no]: ``` Configuring PowerDNS ERROR: Unable to create user for powerdns database Error: ``` Yes, no message was shown... after some time looking at the code and trying different things I compared the code from `installer_base.lib.php` with `gentoo.lib.php` which seems to be more up to date. I applied the following change to the `installer_base.lib.php` file and everything worked perfectly: ```diff diff --git a/install/lib/installer_base.lib.php b/install/lib/installer_base.lib.php index 335bfa5b..6da2db71 100644 --- a/install/lib/installer_base.lib.php +++ b/install/lib/installer_base.lib.php @@ -2036,8 +2036,8 @@ class installer_base { } //* Create the ISPConfig database user in the local database - $query = "GRANT ALL ON ??
