chrooted sftpuser:www-data - can't update - THX!

[webminbwn]

cannot update

Copy file failed

sudo chown -R >>sftpuser<<:www-data /path/to/webroot/tmp
(not necessary but I wanted to show its a chrooted sftpuser, member of www-data the webroot belongs to)
This I did though:
sudo chmod -R 775 /path/to/webroot/tmp
