Yeah you better do full install with ubuntu-device-flash or flash_tool.
Delete everything under /cache/recovery and run
$ ubuntu-device-flash touch --channel ubuntu-touch/stable/bq-aquaris.en

It's hard to say what succeeded and what failed at this stage.
There is about 400MB free I think, but it's going fast once you start
installing development tools.
