I assume you upgrade on Linux or some other *ux and run the launchpad from a shell window. Please consider to provide the information about platform and so forth the next time.

You need to set your Display Variable such that X-Windows is able to run.

Hi Amit,

If you can't get x-windows to run you might be able to perform a command line install.

Hi Amit,

The "The ... package specified in the ...silent-install-server.xml file cannot be found." Error usually means you are not pointing to a valid repository in the silent-install-server.xml
You need to replace ..\repo in the following line with the RTC install repository
<repository location='..\repo' temporary='true' />
Note the install repository is a different download than the web installer.

If you have access to jazz.net you can install from there using this technote
http://www-01.ibm.com/support/docview.wss?uid=swg21576781

But you will need to save the jazz.net password to a file on a client where you can start IM in gui mode.

You can use this URL to install the 4.0.3 server from jazz.net:
'https://jazz.net/downloads/clm/4.0.3/4.0.3/install-repository/clm-offerings/repository/repository.config'
<repository location='https://jazz.net/downloads/clm/4.0.3/4.0.3/install-repository/clm-offerings/repository/repository.config' temporary='true' />

If you don't have access to jazz.net from that server you will need to download "Jazz Team Server and CCM, QM, and RM Applications..." from the "IBM Installation Manager Repositories" section.
https://jazz.net/downloads/rational-team-concert/releases/4.0.3?p=allDownloads

Unzip that file and change the '..\repo' value to the directory that has the repository.config file in it.
For example
<repository location='/tmp/JazzInstallRepo/repository.config' temporary='true' />
