Could someone interpret this?

I am trying to upgrade my word press installation and am getting the following error:

Warning: ftp_rawlist(): open_basedir restriction in effect. File(/tmp) is not within the allowed path(s): (/usr/local/pem/vhosts/160516) in /usr/local/pem/vhosts/160516/webspace/httpdocs/wp-admin/includes/class-wp-filesystem-ftpext.php on line 203 Warning: ftp_rawlist(): Unable to create temporary file. Check permissions in temporary files directory. in /usr/local/pem/vhosts/160516/webspace/httpdocs/wp-admin/includes/class-wp-filesystem-ftpext.php on line 203

Unable to locate WordPress directory.

Installation Failed

Could someone interpret and describe actions to resolve this?

Thanks,
