This problem is fixed in the qtcreator-plugin-ubuntu in the 3.1.1+14.10.20140728.1 version. The backport of this version to Trusty is available in the SDK's Tools Development PPA (https://launchpad.net /~ubuntu-sdk-team/+archive/ubuntu/tools-development) and it will be released after testing and dogfooding.
The problem indeed is that click destroy does not delete the chroots if they have active mount points or the click chroot is severly broken. In this case I think it is perfectly OK to fall back to the file system level solution and lazy unmount the mounts and remove the chroots from the file system. ** Changed in: qtcreator-plugin-ubuntu (Ubuntu) Status: New => Fix Released -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to click in Ubuntu. https://bugs.launchpad.net/bugs/1346723 Title: Cannot delete my chroot.
