When attempting to upgrade from 14.10 to 15.04 I'm running the following command.
sudo do-release-upgrade
The command is failing silently with no output on the command prompt.
What should be my first steps to troubleshoot this? Are there logs somewhere that I can check? I'm accustomed to more feedback from failing programs.
Edit 1: more info...
The command returns after about one second, and the exit code is 139, which indicates a segmentation fault.
Edit 2:
After running the following command
sudo strace -o do-release-upgrade.strace do-release-upgrade
You can find the strace output here: http://pastebin.com/hb5zthbb
sudo apt-get upgrade
?sudo apt-get install python3-pudb
