Metacat

I followed the instruction on Mike's email to install metacat in naples.nceas.ucsb.edu, which is a 64-bit machine:

To try it out, edit /etc/apt/sources.list and add the following two lines (or set it up
in the Software Sources GUI):

deb-src   http://indus.msi.ucsb.edu/apt  sid  main  contrib  non-free
   deb         http://indus.msi.ucsb.edu/apt  sid  main  contrib  non-free

Then refresh apt-get by typing

sudo apt-get update

Now type

apt-get install metacat

However, when i ran "sudo apt-get update" and i got the error:
