I'm also having this problem. It is effecting my ability to update/install any other packages on my production Database server! Please Help!

[Brian Thomason (brian-thomason)]

Have you tried a dpkg --purge db2exc

Also, does this occur with the package from the partner repository as well?

[silbermm (silbermm)]

I have actually figured it out. The post and pre actions were erroring out...

Recognized similar problem while installing the package db2exc_9.7.2-10_i386.deb, obtained from http://archive.canonical.com/ubuntu ludid partner.

First, the installation proceeds until Synaptic returns an error: "Sorry, the package db2exc_9.7.2-10 failed to install or upgrade".
But according to attached extract from /var/log/apt/term.log, everything seems to succeed except a last couple of statements:
   'unknown': unknown terminal type.
   dpkg: error processing db2exc (--configure):
   subprocess installed post-installation script returned error exit status 1
And then, db2exc is anyway in place and working properly at this stage.

Someone also suggested to check and modify the script /var/lib/dpkg/info/db2exc.postinst - but I have no clue why and how, or if perhaps the 'clear' statement in row 348 is critical.

The other issue, however, is that with every scheduled pass of Update Manager I'm getting another "Setting up db2exc"-attempt, which finally claims to fail again, but which creates always new "dasusrX" users instead.
And even more strange: this also happens regardless of the package being locked as pinned in Synaptic to prevent any further updates.

I am having somewhat the same problem..
I installed db2 and it failed saying
 Setting up db2exc (9.7.1-3hardy1) ...
 * Setting DB2 library path... [ OK ]
 * Registering installation in the DB2 global registry... [ OK ]
 * Creating new group and user for Database Administration Server... [ OK ]

dpkg: error processing db2exc (--configure):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 db2exc
E: Sub-process /usr/bin/dpkg returned an error code (1)

And since then i am not able to install/update anything. It always retrns an error "E: db2exc: subprocess installed post-installation script returned error exit status 1".And I am using ubuntu 10.04 lts..32 bit..
I do not know anything about the postrm or postint files and what to do with them.. But a post suggested to do some changes in the /var/lib/dpkg/info/db2exc.postrm file.

But nothing happened even after that.
Please suggest something.
