If you have installed the 4.3.2 php, your in for a little adventure in order to upgrade to the latest Webppliance. Here's what we had to do just to be able to upgrade.
BTW, these instructions are to be done at your own risk. I cannot garuntee what affect this will have on your box as we all have unsupported configurations were trying to recover from.
Ok, back to the instructions...
If you are on webpliance 3.5.15 do the following
First lets fetch the original rpms.
cd /home/admin
mkdir orig.php.ensim.3.5.15
cd orig.php.ensim.3.5.15
wget ftp://ftp2.ensim.com/apt/ensim/LWP/3.5.15...nsim10.i386.rpm
wget ftp://ftp2.ensim.com/apt/ensim/LWP/3.5.15...nsim10.i386.rpm
wget ftp://ftp2.ensim.com/apt/ensim/LWP/3.5.15...nsim10.i386.rpm
wget ftp://ftp2.ensim.com/apt/ensim/LWP/3.5.15...nsim10.i386.rpm
wget ftp://ftp2.ensim.com/apt/ensim/LWP/3.5.15...nsim10.i386.rpm
wget ftp://ftp2.ensim.com/apt/ensim/LWP/3.5.15...nsim10.i386.rpm
wget ftp://ftp2.ensim.com/apt/ensim/LWP/3.5.15...nsim10.i386.rpm
wget ftp://ftp2.ensim.com/apt/ensim/LWP/3.5.15...nsim10.i386.rpm
wget ftp://ftp2.ensim.com/apt/ensim/LWP/3.5.15...nsim10.i386.rpm
wget ftp://ftp2.ensim.com/apt/ensim/LWP/3.5.15...nsim10.i386.rpm
wget ftp://ftp2.ensim.com/apt/ensim/LWP/3.5.15...nsim10.i386.rpm
wget ftp://ftp2.ensim.com/apt/ensim/LWP/3.5.15...msim10.i386.rpm
wget ftp://ftp2.ensim.com/apt/ensim/LWP/3.5.15...95.2-2.i386.rpm
Now lets uninstall php 4.3.2.
rpm -e --nodeps expat `rpm -q -a | grep php- | grep -v webppliance|sort`
Now lets reinstall the original php
rpm -ivh /home/admin/orig.php.ensim.3.5.15/*.rpm
That's it, you should now be able to upgrade to ensim 3.5.16 so that you can get to 3.5.17
Good luck!
Oh, after you upgrade to ensim 3.5.17 and you plan to reinstall the 4.3.2 patch, I strongly recomend you back up a copy of all the new original php files so you can revert back for the next ensim upgrade:
Here's the steps to do that:
cd /home/admin
mkdir orig.php.ensim.3.5.17
cd orig.php.ensim.3.5.17
cp /path_to_wherever_you_extracted_LS-3.5.17-2.tar.gz/LS-3.5.17-2/LS-3.5.17-2/php*.rpm .
