Bug Description
On a fresh Xenial install, with encrypted home (ecryptfs) creation of click chroots always fails:
$ sudo click chroot -aamd64 -fubuntu-sdk-15.10 create
[...]

This leaves me in an inconsistent state where a subsequent exists will claim the chroot doesn't exist, but both create and destroy fail:
$ sudo click chroot -aamd64 -fubuntu-sdk-15.10 create
FileExistsError: [Errno 17] File exists: '/var/lib/

It's not the same as bug 1427264 and the work-around doesn't affect it.

Work-around:
In the file /usr/lib/
Change the last line of the maint() method to always return 0:
def maint(self, *args):
...
return 0 # ret
With this in place you'll see the errors but can successfully use click chroots.
