on 4 September 2017
Weekly status for the week of the 28th to the 3rd of September 2017.
Introduction
The main focus for this past week has been the preparation for LXC 2.1.
We’ve now issued a call for testing and expect it to release tomorrow (Tuesday).
On the LXD side of things, we’ve been working through bug reports quite a bit, did some internal refactoring and been slowly working our way through our stable branch backlog.
As for the LXD snap, a new lxd-migrate tool has been written which will allow users to move data from an existing LXD installation over to the LXD snap, updating all needed database entries and storage specific data in the process. This is currently only available in the edge channel as we’re still working on manual and automated testing for this feature.
Open Source Summit – Los Angeles

Distribution work
This section is used to track the work done in downstream Linux distributions to ship the latest LXC, LXD and LXCFS as well as work to get various software to work properly inside containers.
Ubuntu
- LXC 2.0.8-0ubuntu7 includes a cherry-pick of the Ubuntu 17.10 template bugfix.
- LXD 2.0.10-0ubuntu1~16.04.2 was released to Ubuntu 16.04 LTS users.
- LXD 2.0.10-0ubuntu1~14.04.2 was released to Ubuntu 14.04 LTS users.
Snap
- Worked on a new tool to do .deb to .snap migration of an existing LXD daemon, including support for upgrading versions in the process and supporting the 2.0 track. The new tool has been pushed to the edge channel for now, awaiting additional manual and automated testing before we roll it out to the other channels.
