Question Kunena 3.0.6 update fails from 3.0.1 with Joomla 3.3.3

I tried to update manually Kunena from version 3.0.1 to 3.0.6 with Joomla in version 3.3.3.
The installation is locked on the step "Installation preparation". I don't know what I have to do to continue the upgrade.

I tried to uninstall and reinstall the component. I tried to do the same Kunena upgrade on a other website (with the same setup). But still without success.

What can I do to succeed the Kunena upgrade?

Thanks in advance for your help.

first try by installing from url.

joomlacode.org/gf/download/frsrelease/19...3.0.6_2014-07-28.zip

Thanks for your help.

I reinstalled the component with your link.

I am exactly in the same situation: locked on the step "Installation preparation"

Ok then there is a plugin broken on your site.

Please disable all none joomla plugins. And then use the extension updater. and update kunena.

Ok, I disabled all none joomla plugins and reinstalled Kunena again by installing from URL.

I don't have any extension to update in 'Extension updater'.

I am still locked on the step "Installation preparation"

can you create for me an super admin account. then I will take a look.

Thank for you help, but I can't give you this kind of access.

I restored a old version of my website with Kunena in version 3.0.1, but with the bug:

Duplicate entry '63-9082' for key 'user_topic_id' SQL=UPDATE `xxx_kunena_user_read` SET `topic_id`='9082',`category_id`='11',`message_id`='17979',`time`='1407172175' WHERE user_id='63'

Do you think It's possible to find a Kunena version, without this bug and without the lock on the step "Installation preparation". Kunena 3.0.3 ?

If you have another idea ?

Thank again for your help.

can you make a screenshot from the error. So click on details on the the installer.

There is no error in the installer. Only the message 'Preparation installation' and nothing more.

can you check the php error log.
