Error: Couldn’t load XPCOM Zimbra Desktop

Zimbra desktop installation on a brand new installation of Ubuntu/Linux mint 64 bit release always fails (Tried on Ubuntu 14.04/14.10/Linux Mint 17 etc) due to the lack of 32 bit architecture support.

I confirmed it by running Zimbra desktop with ia32-libs added to the distribution and manually running zdclient as follows:

$ /opt/zimbra/zdesktop/linux/prism/zdclient -webapp “/home/techfiz/zdesktop/zdesktop.webapp” -override “/home/techfiz/zdesktop/zdesktop.webapp/override.ini” -profile “/home/techfiz/zdesktop/profile”
Couldn’t load XPCOM.

This is mainly because the way 32 architecture support used to be enabled on the distro’s. Earlier installing ia32-libs package was quire easier via apt-get. Now the best way to install 32 bit architecture support is as follows:

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install ia32-libs

Now try opening Zimbra desktop, it works like a charm.

Add 32bit package support for Debian/Ubuntu/Mint

Many applications which look for 32bit packages on your Debian/Ubuntu/Mint packages would need ia32-libs packages. Earlier it was possible to get this package installed and later on it has been removed from all distributions. The best way to get back the 32bit package support is to add the architecture to dpkg as follows:

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install ia32-libs
