I'm trying to install a tool from the public toolshed into my local galaxy instance. However, the installation process stops with the following error:

and all the subsequent tool dependecies also fail to install with the same 'TypeError'

Seems like the tool is no longer available in the repository?

(Galaxy v15.10 - Ubuntu 14.04.03 LTS)

Hi Matthias,

the tool is there, the problem is that pixman is not correctly installing for you. Can you try to install this special repository and maybe the pixman 0.32.6 as well and tell us if you see any specific error message?

Hi Björn,

First of all, a very happy new year! Sorry it took so long for me to reply, but I had some vacation planned during the holidays.
Indeed, installing both pixman and freetype separately seems to have fixed the issue. It seems there is an issue with the dependency handling when installing a tool.

Anyway, it's fixed now, so thank you very much!

PS: any idea where the TypeError comes from? I'm keep on getting the same error message when installing different tools. Could it be an issue with Python?

I guess this is more an issue of the encoding of your database. Can you enable UTF-8 encoding?
