Does not connect: exceptions.TypeError: get_ssl_context() takes exactly 2 arguments (1 given)

[Karl Hegbloom]

As of either yesterday or today, syncdaemon will not connect. In ~/.cache/log/syncdaemon-exceptions.log I find:

Ok, sorry. I just updated again, and you've fixed it. Thank you.

I make use of the u1sync tool, and as of 6th June I'm getting this:

[ScaryTom (t-denley)]

hmm... seems that my vesion of context.py does not match that in the source of https://launchpad.net/ubuntu/+source/ubuntuone-storage-protocol/3.0.0-0ubuntu1, even though I have version 3.0.0-0ubuntu1 installed

/usr/lib/python2.7/dist-packages/ubuntuone-storage-protocol/ubuntuone/storageprotocol/context.py

line 98:

[dobey (dobey)]

Tom, Surely you have 3.0.0-0ubuntu1.1 installed?

I'm having the same problem.

Confirmed by multiple users.

BTW why am I still listed as Original-Maintainer on Protocol?

[Karl Hegbloom (karl.hegbloom)]

I thought this one was already fixed? Hmmmm.

Karl, it is already fixed in ubuntuone-client, however it is not fixed in u1sync as it is a not well maintained additional tool, which is not generally recommended. The cause is the same, but the trace is slightly different there.

[Kevin Ray (kevindanray)]

The issue has been resolved for both of my workstations with the latest updates.

[ScaryTom (t-denley)]

Having taken the latest updates, I am now getting this:
Traceback (most recent call last):
  File "/usr/local/bin/u1sync", line 28, in <module>

[ScaryTom (t-denley)]

I'm an idiot, ignore my last post.

For some reason I removed the python-ubuntuone-client package and didn't re-install it. With that done, I'm back to the original exception:

[ScaryTom (t-denley)]

Thanks for the fix. I've updated my backup server, and will report back with results tomorrow, after the overnight run.

[ScaryTom (t-denley)]

I can confirm that the latest version works correctly.

[Mystic-Mirage (mystic-mirage)]

Hi! I have ubuntuone-client 3.0.1-0ubuntu1.0.1 installed but I still getting same error as in bug description.

[Mystic-Mirage (mystic-mirage)]

Sorry. My error is reverse of this bug. I getting this:
get_ssl_context() takes exactly 1 argument (2 given)

Problem solved by replacing:
ssl_context = get_ssl_context(self.disable_ssl_verify, host)
to
ssl_context = get_ssl_context(self.disable_ssl_verify)

[Mystic-Mirage (mystic-mirage)]

Just ignore my posts. The problem was about non-propertly upgraded precise from oneiric because of ubuntu one ppa.
