As an update to my comment above, while the release upgrader hung and did not finish the upgrade, it *did* disable all my ppa's and switch over to the Xenial repositories, which ended up leaving my system broken next time I tried pulling in updates (thinking the upgrade had failed completely and the system was still using Trusty repositories). I'm not sure what packages are at Xenial versions and what packages are at still at Trusty versions, there seems to be a mix.
So it seems I can't expect Ubuntu to upgrade between LTS versions without barfing all over itself. Gee, what fun. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/1511875 Title: Can't upgrade from 15.10 Wily to 16.04 Xenial in LXC container Status in lxc package in Ubuntu: Invalid Status in ubuntu-release-upgrader package in Ubuntu: Triaged Bug description: When I try to upgrade from 15.10 Wily to 16.04 Xenial (actual development version) within an LXC container, the upgrade script hangs at the message „Calculating the changes”. 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.
