Ok, I have installed these three ext

  rgneslinks rgnewsce tt_news .

Now the upgrade is fine. But again got error due to multicolumn

````````````````

Fatal error: Call to undefined method TYPO3\CMS\Core\Utility\GeneralUtility::readLLXMLfile() in 
typo3conf/ext/multicolumn/lib/class.tx_multicolumn_div.php on line 211

`````````````````

So also uninstall it. Now at BE no page tree is available and at FE the eror is

````````````````````````
Fatal error: Class '\TYPO3\CMS\IndexedSearch\Hook\TypoScriptFrontendHook' not found in 
typo3_src-6.0.0beta2/typo3/sysext/core/Classes/Utility/GeneralUtility.php on line 4154

````````````````````````````

Any clue what is happening inside the version 6beta2 ?
