When running text mode installer installer, the field is not wide enough to type in http://blahblah:3128 and the installer complains about the field must be a url.
installer cd was livecd-i686-installer-2006.1.iso dated 8/11 md5sum is e5aa30062718c8110c09ced6902be344 This could be critical for a network install. But it is fairly easy to work around it.
Thank you for reporting this. I will fix the problem with the width. You were, however, supposed to only type the address part and not the http:// part. I will try to make this more clear in the instructions b/c I can understand it may be unintuitive to not type the http:// part even though we already know it's http:// because it's an HTTP Proxy.
This should now be fixed in SVN.
