I am trying to use Ubuntu One behind an authenticating proxy at work on Windows XP. I have Ubuntu One 3.0.2, but it doesn't work, I don't know if it is because it does not recognize the system proxy settings ("Internet options" on the Windows control panel) or because it does not know how to authenticate (it doesn't ask me for proxy user/password in any case).

The result is that it won't login, when I can login with no problems on my Ubuntu One under Ubuntu 12.04 at home (no proxies, though).

I saw there is a controversial bug about proxy support in Ubuntu One, but even though there seems to be a partial fix at least for the Linux client, it is not clear whether that affects the Windows client as well.

The Ubuntu One FAQ states that "the 3.x version of the Windows client will have proxy support", but that's the current version and the one I'm trying to use. Is there anyone who could make it work on Windows, or knows what's the current status?

Thank you in advance.

The 3.x version of Ubuntu One added support for most common types of proxies, both for Ubuntu and for Windows.

If you want to set up a proxy under Windows, make sure you have unchecked the "Automatically detect settings" option inside "Internet properties" -> "Connections" -> "LAN settings", and that you have set up the address and port for your proxy servers too:

After changing proxy settings in Windows, Ubuntu One may not pick them up right away, so you need to either reboot or end every process that starts with "ubuntuone".

As I wrote in the main description, I have the proxy set in the "internet settings" section of the control panel. I have other programs working with those proxy settings (internet explorer, to name one), but Ubuntu One does not use them. In the "sign me in with my existing account" dialog I enter my Ubuntu One user/password and then, after pressing "sign in" I have "the authentication failed" immediately. Mind you that if Ubuntu One would have used the proxy settings, it should have asked me for the proxy username/password, which it didn't. Should I file a new bug? – Trucoto Jul 10 '12 at 12:57
I already did: – Trucoto Jul 10 '12 at 15:15
Followed the instructions with ubuntu one 4.2.0 windows installer. It asked me for login and password of the proxy, and then started to connect endlessly without connecting. – umdhlebe Jun 7 '13 at 9:11
