[Jim French]

system crashes when rebooting after running software updates in 16.04.2 to 16.04.3 purple screen shows and will not proceed. I tried to re-install 16.04.2 alongside 16.04.3 and the the partitioning failed with exit code 141. Then the installer said it crashed and would not continue.

Thank you for taking the time to report this bug and helping to make Ubuntu better. We noticed that you were installing the LTS version of Ubuntu using an older version of the installation media. The latest point release of 16.04 is 16.04.3. Please try installing from that version of the installation media and see if that resolves your issue. Thanks in advance!
