After Ubuntu 15.10 to 16.04.1 upgrade, baikal doesn't work.

[Godi22]

Hello,

I have Ubuntu 15.10 upgraded to 16.04.1 and switched to php7.0.

On the server there was also a baikal 0.2.7 installation. I did an upgrade to 0.4.6 and the upgrade porcess was successfully. But the clients doesn't synchronize with the baikal server.

Now I created a new mySQL Database and installed a new baikal 0.4.6 version, but I have still the same problem that Thunderbird can't sync the data.
When I browse to my addressbook in Firefox I get the following message:

Error: Call to undefined function Sabre\HTTP\mb_detect_encoding() in /var/www/html/baikal/vendor/sabre/http/lib/functions.php:434

10 {main}

On an other server with a working baikal 0.4.6 installation, sabre returns a table with the available cards.

What can I do, that the new baikal works on Ubuntu 16.04.1?

Install the 'mbstring' extension for php on ubuntu. Surprised that this is not yet the default!
