I just had this error on Juanty... i am not sure why because there are four computers on the network and mine is the only one called matthew- desktop, anyways i followed the workaround in this thread and things are ok now.
I think if the error prompt for this type of issue should be the following: == <b>Ubuntu is unable to connect to %some-computer.</b> It is possible the hostname %my-hostname is already in use on the network. A hostname is a unique name that identifies your system on a Local Area Network (LAN). To connect to %some-computer please enter a new and unique hostname: New Hostname (example: matthew-desktop2): _______________________ [_______________________] [Cancel] [Continue] <- Continue should become sensitive only when a new and unique hostname is entered == -- Cannot retreive share list if samba client and server have the same hostname https://bugs.launchpad.net/bugs/338411 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
