Both tmp directory are writable and in the configured paths (if I’m reading this correctly).

What am I missing?

@Paka

Temporary directory /tmp is not present or writable

It says you:

@Paka

PHP is_writable(): open_basedir restriction in effect. File(/tmp) is not within the allowed paths

And confirms:

@Paka

/usr/share:/usr/share/php5:/dev/urandom:/var/www/clients/client1/web62/web/nc) at

You need to review your PHP ini config, to add the folder /tmp in the directive open_basedir.

2/ your folder tmp into the data directory is different than /tmp

3/ restart your web server, or php instance

Hi Paka,

as 42IO said, the error message is referring to your open_basedir parameter from your php.ini.

This is the explanation for open_basedir

; open_basedir, if set, limits all file operations to the defined directory

So you can either just put a semicolon in front of the parameter, or you need to add the correct folder paths, for it to work correctly.

Please make sure to either reload or restart your Apache, after you made changes to your php.ini

@CFelix

Please make sure to either reload or restart your Apache

Yes, restart your web service (perhaps, it’s Apache, or nginx, or whatever…)
( I forgot this point)

Thanks both to CFelix and 42IO!

Turns out it was an ownership issue. The thought woke me in the middle of the night.

The install directions had ownership set for all files and directorys as:

chown -R www-data:www-data

I should have mentioned the service being used utilizes ISPConfig for management although I personally work a great deal from the command line.

ISPConfig allocates an owner ID to each domain. web01 … web78, etc.

So i reset ownership to the corresponding ID used for the domain (let’s say ‘web112’):

chown -R web112:www-data nextcloud

Nextcloud loaded right up in the browser.

Again thanks to both of you for your time and feedback.
