Public bug reported:

The Ubuntu Software Center attempts to ping the repository host on
startup to check for internet connectivity (when NetworkManager is not
present). However, the software-center uses the complete network
location (urlparse's netloc) as the ping destination - which causes
problems if the location contains a port component (or basic
authentication).

For example, our repository url is http://apt.mr.lan:3142/ubuntu. When
we start software-center, it attempts to ping "apt.mr.lan:3142", which
fails, and so the Install button is grayed out.

Log output:
INFO - Attempting one time ping of apt.mr.lan:3142 to test if internet 
connectivity exists.


The following patch uses urlparse's hostname instead of netloc (also attached):

After applying patch:
