It is true that there is no pyodbc package in Ubuntu. However, using
python-setuptools we can do an easy_install of pyodbc. This method will
compile pyodbc from source.
First, you need to apt-get install python-setuptools. Then, make sure you
have all the dependencies. You need unixodbc, unixodbc-dev, and
build-essential. You also may need to get python-dev. Apt-get all of
these packages and then run sudo easy_install pyodbc. This is the method
that worked for me, I hope you find this useful!
