I had tried to put the DB2 Express-C 9.7.2 on 64-bit Linux system, and I failed either on Ubuntu 8.04 LTS
or on Debian 5.0 (I know it is not recommended/supported solution).
The first and the last problem was related to the db2setup startup error.
It can be seen from the console just like that:
# ./db2setup
DBI1190I db2setup is preparing the DB2 Setup wizard which will guide
you through the program setup process. Please wait.
#
But, there was the trail in the error log:
# cd /tmp
# cat db2setup.err

Let me start from the beginning.
# ./db2setup
WARNING:
Can't use string to find the version of libstdc++.
Check the following web site for the up-to-date system requirements
of IBM DB2 9.7
http://www.ibm.com/software/data/db2/udb/sysreqs.html

The force option "-f sysreq" is used to force the installation ...

The DISPLAY variable is not set properly. Ensure that the DISPLAY variable is set properly and that permissions are set properly to open windows on the display specified, then rerun the command.
#
Even with the -f sysreq there was no visible progress.
Before the installation begins I have installed the libaio1 and libstdc++6 as it was mentioned in the online documentation.
The installation was on the remote server, so to verify that X11 session forwarding works fine I had to install xauth and use the ssh -Y option.
# xauth list
digestive.deadsystems.com/unix:10 MIT-MAGIC-COOKIE-1 a957c95c1c862f5314b32e88c5bd9e17
# echo $DISPLAY
localhost:10.0
I have used the xarclock to check that the remote app is being displayed fine on my laptop.
"Can't use string to find the version of libstdc++." -
it was resolved by simple binutils package installation (to get the strings binary).
But, there was no progress yet.
# ./db2setup

#
Then I thought that the /tmp/db2setup.err contains the java related exception, but there is no java vm on the machine.
# java -version
-ksh93: java: not found [No such file or directory]
After the sun-java6-jre installation there was still nothing more.
# java -version
java version "1.6.0_22"

A few search queries more and I have found a tip:
GUI applications, such as the JConsole monitoring tool, on 64-bit Ubuntu with a 32-bit JVM
When running a 32-bit JVM on a 64-bit Ubuntu system, GUI applications do not start because some AWT libraries are missing. To fix the problem, install the 32-bit libraries using the ia32-libs package:
sudo apt-get install ia32-libs
The following exception is thrown if the libraries are not available:
Exception in thread "main" java.lang.UnsatisfiedLinkError: awt (An exception was pending after running JNI_OnLoad)
at java.lang.ClassLoader.loadLibraryWithPath(ClassLoader.java:993)
at java.lang.ClassLoader.loadLibraryWithClassLoader(ClassLoader.java:962)
at java.lang.System.loadLibrary(System.java:465)
... lines removed for clarity ...
If problems are encountered with DNS name resolution, install the package lib32nss-mdns.
But neither ia32-libs nor lib32nss-mdns installation helped me to go further.
The only benefit was the lack of warning message:
WARNING:
The 32 bit library file libstdc++.so.6 is not found on the system.
32-bit applications may be affected.
Then It looked like:
# ./db2setup
DBI1190I db2setup is preparing the DB2 Setup wizard which will guide
you through the program setup process. Please wait.
#
After the additional few hours of digging through the differences between the library sets on two machines,
on which the first have the fully operational DB2 instances and the second is the reported unlucky node, I have pointed the main responsible for all the evil - there was no libxft2. After the apt-get install libxft2 - db2setup has raised from the ashes.
Enjoy.
