Question K 1.7 Update or Installation not possible

Hello,

since 5 days I try to update my K 1.6.4 to K 1.7 on an updated Joomla 1.7 - it is not possible. I tried a lot of ways: Update - fresh install (I deleted all data-tables like kunena-entries in jos_assets, jos_kunena..., kunena-entries in jos_extension, old fb_tables and kunena-entries in jos_menus, all kunena-language-files) - no way is possible. The last error message I got:

Warning: require_once(.../webseiten/test2/administrator/components/com_kunena/libraries/error.php) [function.require-once]: failed to open stream: No such file or directory in /kunden/101705_71083/webseiten/test2/administrator/components/com_kunena/api.php on line 47

Fatal error: require_once() [function.require]: Failed opening required '/kunden/101705_71083/webseiten/test2/administrator/components/com_kunena/libraries/error.php' (include_path='.:/usr/local/lib/php') in /.../webseiten/test2/administrator/components/com_kunena/api.php on line 47

But the error messages are diffrent for every new attempt - it seems for me, that the installation breaks because of another reason I don´t find.

I tried a fresh installation of K 1.7 on the same server with a clean Joomla 1.7 - it works wonderful, no problems. So the server configuration and the power of the systems seem to be o.k.

I tried the installation on all the three ways: by url, about the tmp-directory and by uploadin - nothing works under this configuration (the data-tabes have the prefix j16_ - but that could not be the problem, couldn´t it?).

Do you have an idea what I may try?

Thank you very much
Peter

Hello,

Do you have checked permissions on directoires : /administrator/components, /components and /media ?

The were 750. That was no problem at the fresh Joomla 1.7 and K 1.7 Installation.

But I changed them all (/administrator/components, /components and /media) to the recommended 755. And it seems to me, that the installation-process went a little bit further. No I got a new message:

Error building Admin Menus
Component Install: DB function reports no errors

Fehler bei der Komponenten-Installation!

Can I do something else?

And now, after a new try: I deleted all the entries of kunena in j16_menu, j16_assets and j16_extensions, I get again:

Warning: require_once(/.../webseiten/test2/administrator/components/com_kunena/libraries/error.php) [function.require-once]: failed to open stream: No such file or directory in /.../webseiten/test2/administrator/components/com_kunena/api.php on line 47

Fatal error: require_once() [function.require]: Failed opening required '/kunden/101705_71083/webseiten/test2/administrator/components/com_kunena/libraries/error.php' (include_path='.:/usr/local/lib/php') in /kunden/101705_71083/webseiten/test2/administrator/components/com_kunena/api.php on line 47

Is there a possibility to see for me, why the installation isn´t possible? Or a step by step installation?

Look in your table jos_menu and remove all occurences related to Kunena

Hello xillibit,

thank you for your help!

I removed all kunena-entries in j16(!!)_menu (I don´t think that it is a problem I have j16_ insted of jos_), and now the error message is:

Component Install: DB function reports no errors
Fehler bei der Komponenten-Installation!

But I wonder: there is no folder com_kunena in administrator/components/ or in /components/

And I wonder - in the jupgrade/tmp - installation folder were all the files - I made a picture:
