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. ** Attachment added: "Extract from: /var/log/apt/term.log" https://bugs.launchpad.net/ubuntu/+source/db2exc/+bug/373941/+attachment/1765778/+files/db2exc_inst_log.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/373941 Title: Unable to uninstall package db2exc -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
