Comment 1 for bug 189538

I would like to agree that this is a very serious problem.

I use db2 for work and have just encountered (after upgrading to 9.5 as suggested by ubuntu update) all my existing databases not working, I can't reinstall, I can't remove, I'm completely stuck now.

Preparing to replace db2exc 9.5.0-1gutsy1 (using .../db2exc_9.5.0-1gutsy1_i386.deb) ...
Unpacking replacement db2exc ...
dpkg: warning - old post-removal script returned error exit status 1
dpkg - trying script from the new package instead ...
dpkg: error processing /var/cache/apt/archives/db2exc_9.5.0-1gutsy1_i386.deb (--unpack):
 subprocess new post-removal script returned error exit status 1
dpkg: error while cleaning up:
 subprocess post-removal script returned error exit status 1
Errors were encountered while processing:
 /var/cache/apt/archives/db2exc_9.5.0-1gutsy1_i386.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

I would like to revert back to 9.1.2 or even stick with 9.5, but instead I'm stuck completely...
