Upgrading Plone to a minor release

Hello !
I'm trying to upgrade plone 4.3.1 to 4.3.4.1, I have edited buildout.cfg 55
and then run buildout, I got this error 12
Any help to fix this please ?

Try adding in your buildout.conf in [buildout] section:

index = https://pypi.python.org/simple

If this does not work take a look at this thread.

I’m trying to upgrade plone 4.3.1 to 4.3.4.1, I have edited buildout.cfg

In your buildout example, you're using http://dist.plone.org/release/4.3-latest/versions.cfg which upgrades to 4.3.15, not 4.3.4.1. If you really want to upgrade do 4.3.4, use http://dist.plone.org/release/4.3.4/versions.cfg instead.

Thank you for your feedback, now I'm getting another error

Did you follow @joplono's suggestion as well?

Hello,
Yes I did and it didn't work so I deleted my Plone 3.4.1 and reinstalled Plone 4.3.4.1.
Thank you for your answers !
