Newbie: How do I "change ownership of the folder to www-data"


I’m a total newbie and I had to install owncloud on our apache-webserver. Now I want to change some colours and images.

So I’ve downloaded the master-theme from github and uploaded it to owncloud/apps and modified the info.xml.

Next step is “Don’t forget to change ownership of the folder to www-data” - but I don’t know how to do so. I’ve set permissions to 750 but I don’t think that’s enough??

I didn’t use the poweshell-script because I didn’t know how to that on my webserver.

Plus it says “- EXCEPTION
- OC\IntegrityCheck\Exceptions\MissingSignatureException
- Signature data not found.”

Can someone please help a lost girl?

thx a lot!

chown -R www-data:. <folder_name>
