After successful upgrade Ubuntu Linux from 9.04 (Jaunty Jackalope) to 9.10 (Karmic Koala) on my laptop, I’ve found that my TIBCO Designer is no longer works here:

./designer: error while loading shared libraries: cannot open shared object file: No such file or directory

I’ve found that isn’t available in Karmic repos anymore but still in Jaunty here: You can download and install it:

sudo dpkg -i libstdc++5_3.3.6-17ubuntu1_i386.deb

After that Designer runs great on Karmic.
