After latest update of 11.10, Ubuntu One is not syncing anymore, even after resetting the password. The error message is:

An exception representing an authentication failure.

Also after this update yesterday, the time is one hour too early and cannot be adjusted.

Any idea?

You're going to need to provide more information about the time issue. Also, where did you see that error message? – webm0nk3y Nov 23 '11 at 21:29

Precisely, that error is caused by the time being wrong :-)

I don't know what the reason for the error but it's probably a timezone, DST issue that can be fixed by installing and enabling ntp and updating the system.

Hope it helps!

Thanks you were right. The time came back to normal by itself and fixed the problem. I guess there was a problem syncing with the server. – Denis Nov 25 '11 at 14:38
