This appears to be a missing dependency on the Python module "six"
which is used to help write code which will work under both Python 2
and Python 3.

This is likely a recent regression - hopefully one of the Galaxy team
can comment on this, likely the Tool Shed definition for this tool needs
a minor tweak (and then you can apply the update via the Galaxy
Admin controls within your browser).

Not that I personally am aware of, no. There are optional disk quotas to
encourage users to remove (delete) old data.

Yes please, with useful email subjects would be best.
