Status changed to 'Confirmed' because the bug affects multiple users.

[Václav Šmilauer (eudoxos)]

Is there a workaround for this bug, given its importance? (Even if it should consist in adjusting a few lines of sources)

[Vincent Ladeuil (vila)]

@eudoxos: Yes, see https://code.launchpad.net/~andidog/bzr-webdav/trunk/+merge/96339

I will cut a new release for bzr-webadv asap.

[Axzel Marin (axzelmarin)]

Today i installed lubuntu 12.04 beta 2 and tried to upload some changes on a bzr branch to my company server got the same error mentioning ca_certs the thing is i'm using http+webdav insted of https, any idea when this fix will be uploaded to 12.04 before release, i really need to update my branch.

Unfortunately, this bug can still be found in trusty, here's the traceback:

@Khaled:

It seems like you're using an outdated version of the plugin.

'bzr plugins -v' will report where you get that plugin from, can you paste the relevant output here ?

[Khaled Blah (khaled-blah)]

Here's the output you asked here (posting it in full):

This is on u14.04 beta-2 machine with plugins from the ubuntu repository. I think that should be a current version.

[Khaled Blah (khaled-blah)]

FYI this bug still persists on u14.04.

[Khaled Blah (khaled-blah)]

Any news on this?

[Vincent Ladeuil (vila)]

Yes, sorry for the delay, I'm trying to find the right people to help me packaging the latest bzr-webdav version into ubuntu.

In the mean time, running from source is your best option.

[Khaled Blah (khaled-blah)]

Thank you for your efforts, Vincent!

[Sethu N Madhavan (sethumadhavan)]

Do we have updated pywbem module with this. say 0.7.25 or so?

[Khaled Blah (khaled-blah)]

Since there's no progress on this bug I am going to post a patch which solves this problem for me. I only tested it on lucid (10.04) though but I believe it will also work on newer versions.

The attachment "_urllib.py.patch" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.
