No chance to update on my local machine and on my live site. On the staging site it works but that's the same server as the live site.
I've cleared the caches and checked the logs.
Local there is only this error:
2016/06/19 19:41:01 [error] [application] Error in Craft\Et::phoneHome. Message: Cannot overwrite an existing license.key file.
But I run the site in DEV Mode.
Any ideas? I'm a bit unhappy about it :/
