i can't install any extension. Magento Connctor 2.0 stops the Installing Process at 'Checking dependencies of packages' There isnt any other thing showing up.
I already checked the file permissions(setting everything to 777 wouldn't help). I followed This and nothing Changed. After Hours of googleing and testing I made a fresh Install and same Problem again.
So i found the Failure..... Someone Installed the domain for typo3 not magento... Thanks everyone for your Help :)
