Public bug reported:
Hi,
this has puzzled me for a while and I think I now at least have enough data to
report it for discussion.
It seems that when I sync images they get created without the right
permissions/ownership?
Effectively I see after a sync of images that they look fine in a query:
uvt-simplestreams-libvirt query
release=xenial arch=amd64 label=daily (20160914)
release=yakkety arch=amd64 label=daily (20160914)
Those are the images of yesterday (this will become important)
And in the FS those look like
ll
/var/lib/uvtool/libvirt/images/x-uvt-b64-Y29tLnVidW50dS5jbG91ZC5kYWlseTpzZXJ2ZXI6MTYuMDQ6YW1kNjQgMjAxNjA5MDk=

All fine and working.
But on a subsequent sync that wants to unlink those uvt is failing, the same
happens for a purge.
uvt-simplestreams-libvirt purge
Traceback (most recent call last):

Permission denied
I wonder if something in my setup is odd - e.g. that the permissions
shouldn't be this way to begin. And I wanted to discuss that before we
debug deeper into what is happening in the code while executing.
