Unable to install

[anonymous]

Ubuntu 14.04, Trac 1.0.1. Plugin installed from svn with no problem, upon enabling the plugin it appears to enable, however running trac-admin <environment> upgrade results in error:

  Error: AttributeError:

(and nothing else).

Creating a ticket subsequently results in error:

  OperationalError: no such table: default_image

Any clues on how I get this working...?

It is probably due to the method of checking for table existence. We've seen similar problems surface in Trac 1.0 and later.

What plugins do you have installed, and what are their versions? This information about be found on the /about page.

What database backend are you using?

In 13934:

Fixed checking for table existence in Trac 1.0 and later. Refs #11754.

It installs now, but there is another problem:

Trac detected an internal error:

IOError: decoder zip not available

It looks like it's probably an installation issue: ​SO:9073732. Let me know if you have trouble getting it working.
