Fixed in trunk in http://bazaar.launchpad.net/~apport- hackers/apport/trunk/revision/2890
I tested it with /dev/nvram on amd64 (I just saw that this also exists there) and it works now. If you want you can apply this simple fix inline in /usr/lib/python3/dist-packages/apport/hookutils.py for testing, but I'll upload a stable release update for this too. ** Changed in: apport (Ubuntu) Status: Triaged => Fix Committed ** Also affects: apport (Ubuntu Utopic) Importance: Undecided Status: New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to apport in Ubuntu. https://bugs.launchpad.net/bugs/1370259 Title: apport fails to collect nvram specific information -- attach_root_command_outputs() does not work for binary data Status in apport package in Ubuntu: Fix Committed Status in apport source package in Utopic: In Progress Bug description: ---Problem Description--- apport fails to collect nvram specific information ---uname output--- 3.16.0-10-generic Machine Type = POWER8 ---Steps to Reproduce--- 1) Install Ubuntu 14.10 in Power non-virtualized environment. 2) Install apport package 3) Run following command to verify if apport collects power specific information. apport-cli -f -p linux-generic --save=/home/sachin/linux.apport The command fails with following error : root@lep8d:/home/sachin# apport-cli -f -p linux-generic --save=/home/sachin/linux.apport *** Collecting problem information The collected information can be sent to the developers to improve the application.

I would think using the function add_tar() creating a tar file and copying the content as a ascii file at end of apport output file more appropriate. One dummy question remaining, how getting the tar file from the ascii output file if we need to ? ( that's also true to validate the content of the DeviceTree tar file).
