I am having trouble connecting to Ubuntu One. I have gone to System > Preferences > Ubuntu One and entered my account information. All seems well at this point. Then when I go to the Devices tab and click Connect, it grays out for about 3 seconds and does nothing.

I have tried reinstalling, rebooting, removing the machine from my account without any success.

Any ideas on other things to try?

FYI: I'm using Ubuntu 10.10.

  • I'm having similar problems. Try using u1sdtool --status to see what results you get. I'm getting errors.

  • Installing and running magicicada is also generally a really good bet for u1 problems - it shows you what's going on.

I tracked down how to fix the problem. It appears that this is somewhat of a known bug. I was able to solve the problem by disconnecting the Ubuntu One account from the computer (by removing the computer from the account) and then deleting the Ubuntu One folder and ~/.local/share/ubuntuone folder, it cleared all of the configuration and when I reconnected the account, all was well.

  1. Log in at: https://one.ubuntu.com/ If you succeed, it means that the login details are correct.
  2. Check it out:
    • logs (eg messages),
    • firewall (?)
  3. Install Wireshak and check traffic to the server and Ubuntu One
