/usr/lib/python2.7/dist-packages/pylxd/model.py:116: UserWarning: Attempted to set unknown attribute "description" on instance of "Container"

I made this changes:

Still build fails:

The script fails to run, probably related to this line: https://github.com/wekan/wekan/commit/075ea1c43d827099e0030c750a4c156bd3340fed#diff-184032a532406b07009403e26f4fc62fR144

probably would be easier to pushd and then popd or do the cp before leaving the dir.

Build was made with sh, so pushd/popd did not work, but I added correct change directory commands to make it work. Thanks!
