I tried to upgrade to 16.04 RC1 running Ubuntu Gnome 15.10 and get error messages that the update manager exited with an unspecified code. Even the bug report choked when trying to report the issue.

Steps to reproduce: 1. Make an LXC container with Wily (quickest option is to use lxc-create -t download, choose ubuntu, wily, amd64/i386). 2. Boot up the container, log in, „apt-get -y install ubuntu-release-upgrader-core”. 3. Start the upgrade with „do-release-upgrade -d”. You will see that the upgrade process will hang at the message „Calculating the changes”. The process which hangs: „/usr/bin/python3 /tmp/ubuntu-release- upgrader-1mpotr5d/xenial --mode=server --frontend=DistUpgradeViewText --devel-release” With strace, it is revealed that the process hangs at a „futex” system call: futex(0x7f4190000c10, FUTEX_WAIT_PRIVATE, 0, NULL This system call never returns, the process must be interrupted with CTRL-C or kill. Upgrading to any previous release within an LXC container works without problems, therefore I consider it as a regression.
