SSLHandshakeError: certificate verify failed

[Nicola Jelmorini]

I have set a daily backup, and until today all has worked very well.
Today instead the backup doesn't work anymore.

These are the error messages that are displayed in the Déjà Dup window:

I use Ubuntu 12.04 64bit.
deja-dup 22.0-0ubuntu2
duplicity 0.6.18-0ubuntu3

Exactly the same symptoms here, although the error messages are not 100% the same:

I am also getting the same certificate verify failed issue.

[Nicola Jelmorini (jelmorini)]

I have booted my PC right now and the backup has finished correctly. So perhaps the problem is resolved. Someone else can confirm this?

[Val (vk1266)]

Yes, it works now. No error messages. Must have been some kind of problem at Ubuntu One's end.

[Humphrey van Polanen Petel (hpvpp)]

No error messages now, just the Error Code 500 that I have been getting ever since 12.04

[Phil Dobbin (bukowskiscat)]

I can confirm that the last three days (23/10/12 -> 25/10/12) that my backup scheduled for 01:00 just returns a simple 500 server error.

Is there a status page for this service?

p.s. trying to post this message results in a server error. I'll keep trying...

[Michael Terry (mterry)]

The original message about SSL handshake verification failing seems to be resolved. For your status 500 issues, that's bug 882699. I'll mark this as a duplicate.

[Val (vk1266)]

The duplicate status of this bug is likely wrong. The original error messages, and the error messages in post #2, have nothing to do with Error Code 500 and everything to do with SSL handshake verification.

The problem is NOT resolved.

The bug appears intermittently and it looks very much like it's an intermittent problem with Ubuntu One and not the Deja Dup's problem. I experience this problem about once a week, and usually after an hour or two the problem goes away by itself.

[Michael Terry (mterry)]

The people in the bug that had commented about the SSL issue said it went away for them, so the only issue left here was the 500 status error.

But interesting to hear that the SSL issue is still happening. I'll re-open this.
