I've been using Synolody before and just recently bought 8 bay QNAP NAS. I was very disappointed after spending almost full day to try to figure out how to install SVN. I concluded that all post about SVN on QNAP are very old. It appears that SVN can not be installed and used on the latest version of QTS. Is that correct? Is there any way to install and configure SVN? If not is there an alternative?
