It seems to be an error in the post install script as it's only looking for "i[0-9]86" as the machine architecture.

Using "uname -m", my machine (64-bit Ubuntu 12.04) returns x86_64 and this causes the script to fail since it doesn't seem to recognise this string.

Here's what I did to get it to install:
1. Install the .deb and let it fail
2. Edit /var/lib/dpkg/info/icaclient.postinst
3. Replace the line that says echo $Arch|grep "i[0-9]86" >/dev/null with *echo $Arch|grep -E "i[0-9]86|x86_64" >/dev/null (note the -E after grep!)
