Issue with libuuid package during Ubuntu 14.10 upgrade

Got the following error while upgrading from  Ubuntu 14.04 to 14.10

Setting up libuuid1:amd64 (2.25.1-3ubuntu2) ...
chsh: PAM: Authentication failure
dpkg: error processing package libuuid1:amd64 (--install):
 subprocess installed post-installation script returned error exit status 1

The post install script was using the chsh program to change the shell of libuuid user to /bin/false only if it was currently set to /bin/sh.

Changing this manually by editing /etc/passwd allowed the package install to continue as normal and all dependent packages to install also.

I had to do an apt-get update && apt-get upgrade to continue with the installation of updates after this was resolved.


  1. I edited /etc/passwd to set the shell for libuuid user to /bin/false so the chsh program didn' execute during package install and completed successfully.

  2. Could have done the same with:
    sudo usermod -s /bin/false libuuid

  3. However, when you choose not to design and have an object that you simply need to replicate, have the ability to|you possibly can} scan the object in 3D and then print it. Offers a novel set of fashions, studying assets and tutorials to create and share 3D-printable fashions associated to biomedical science. The aim of the project is to facilitate the applying of 3D printing in the biosciences. The flexibility of 3D printing allows designers to make modifications simply without the need to|the necessity to} set up further tools or instruments. It also allows manufacturers to create devices matched to a patient’s anatomy (patient-specific devices) or devices Shower Curtains with very complex inside buildings. These capabilities have sparked large curiosity in 3D printing of medical devices and different merchandise, including meals, household items, and automotive elements.
