Error code #1000: Generic WUI error. AI core finished with exit code 127

    While attempting to run the Expand Webinstall on CentOS 5 (64-bit) the "Uploading AutoInstaller core" completes 100% and then errors with "Error code #1000: Generic WUI error. AI core finished with exit code 127".

    I have discovered that ssh port 22 needed to be opened inbound on my firewall and "Compression yes" added to my sshd_config file.

    I have disabled selinux. Ports 80 and 443 are allowed outbound.

    I run an "Default Deny" firewall. Are there any other ports needed inbound or outbound?

    What does this error mean and how do I resolve it?

    Ok, so I just bypassed my firewall and ruled out that as a cause to the issue.

    For grins I formated and reinstalled my Expand server. Set "Compression yes" again in sshd_config and attempted to do the web install again with the same results.

    I attempted to run the ai_core utility from the CLI and received the following.

    [root@expand tmp]# chmod +x ai_core.sh
    [root@expand tmp]# ./ai_core.sh
    ai_core.sh: error while loading shared libraries: libslang-utf8.so.1: cannot open shared object file: No such file or directory

    [root@expand tmp]# yum list | grep slang
    slang.x86_64 2.0.6-4.el5 installed

    Prior to reinstalling I was getting a popt.so error. Again, popt was installed.

    [root@expand tmp]# yum list | grep popt
    popt.x86_64 1.10.2-47.el5 installed

    Plesk Expand does not support 64-bit OSes yet, as I know.

    We must be on the same track. I have been downloading the 32-bit os version as we were writting. I'll post my results.

    ok, After installing the 32-bit version of CentOS 5 and setting the sshd Compression to yes I am still running into the same error as before with the web installer.

    Error code #1000: Generic WUI error. AI core finished with exit code 127

    uname -a
    Linux expand.domain.com 2.6.18-53.el5 #1 SMP Mon Nov 12 02:22:48 EST 2007 i686 i686 i386 GNU/Linux
    [root@expand ~]#

    New information... I was able to launch the autoinstaller from the shell this time with the 32-bit version of CentOS 5.

    This time the only issue I was having was with the firewall during the download of the packages.

    I placed the server on the outside of my firewall and attempted to use the web installer again without success. So I continued with the install using the autoinstaller from the shell.

    Installation completed without issue and I placed the server behind the firewall once again.

    So it is official that expand does not support Centos 5 64 bits?

    I have not found any official information declaring it
