I'm a newbie trying to do a new installation on my Hostpapa webserver.
I grabbed the PHP file installer called "setup-owncloud.php" then put it into the public_html folder, navigated to it and ran it.
I get the following error:
Warning: scandir(tmp-owncloud1479639574/owncloud): failed to open dir: No such file or directory in /home/(mydomain)/public_html/setup-owncloud.php on line 158
I checked line 158 and it looks like it's trying to rename a folder that isn't there. I wondered if it didn't have the right permissions to create the folder in the first place, so I checked this and gave the setup-owncloud.php folder 755 permissions to see if that would help. No luck.
just use the archive file from https://owncloud.org/install/#edition and extract its content to your public_html. The webinstaller is also just doing the same (and nothing more) so i think it doesn't worth to debug your environment to fix it that the webinstaller is working.
That worked, though now I have another problem. I got a bunch of errors post installation, saying things like PHP "fileinfo" is missting and the WebDAV interface is broken. I dropped my host provider a message and their reply was "no we don't offer WebDAV, we are using Linux".
Time to look for another host provider, or are they being obtuse?
