Apps Unable to perform ADT offline installation

[galapogos]

Hi,

I am trying to install ADT 16.0.1 in Eclipse SDK 3.7.2 in a Mandriva Linux 2011 VM. I've successfully installed Eclipse, and I've downloaded the ADT plugin archive. I've then tried to point Eclipse's "Install New Software" to the archive, which it detects properly. However, when I select all and try to install, it hangs there, with the following regular log messages:

org.apache.commons.httpclient.HttpMethodDirector executeWithRetry
INFO: I/O exception (java.net.ConnectException) caught when processing request: Connection refused
org.apache.commons.httpclient.HttpMethodDirector executeWithRetry
INFO: Retrying request

Why is this happening, and how can I fix it?

Thanks!
