Besides, they're all stock files, I haven't touched any of them, so it wouldn't make sense that I'm the only person in the world unable to get WebDAV working. > But it fixes the lock error we begin with. Somewhat. We already know that Apache cannot write to /var/www/html/webdav , so trying to put the DBLock file there won't work. The fix, not that I'm complaining, relocated the DBLock file to a directory where Apache can write, but it has yet to explain why /var/www/html/webdav *isn't* writeable. But I think we established that Apache *can* write to some directories (like /var/log/apache2/). Just not that one. > To make sure it is the problem please provide > sudo -u www-data touch /var/www/html/webdav/newtest Works. I can read and write whatever I want wherever I want from bash.
