svn: Can't create directory '/db/transactions/0-1.txn': Permission denied

org.tigris.subversion.javahl.ClientException: svn: Can't create directory '/home/svn/myproject/db/transactions/0-1.txn': Permission denied
svn: MKACTIVITY of '/svn/myproject/!svn/act/298deda5-1e01-0010-9e5a-b76b06d1c848': 500 Internal Server Error (http://192.168.1.230)

I got this error when i installed subversion in my ubuntu Desktop.The problem occurs since apache is unable to create directory under repository.

So i have permissions to my home repository as sudo chown -R www-data:www-data /home/svn/.

After that i restarted the apache server.I found the error doesn't happen once again.
