Just add "universe" on the xenial-updates.
只需universe在xenial-updates.
# cat /etc/apt/sources.list.d/*
deb [arch=amd64] http://fr.archive.ubuntu.com/ubuntu/ xenial-backports main
deb [arch=amd64] http://fr.archive.ubuntu.com/ubuntu/ xenial main universe
deb [arch=amd64] http://fr.archive.ubuntu.com/ubuntu/ xenial-proposed main
deb [arch=amd64] http://security.ubuntu.com/ubuntu xenial-security main
deb [arch=amd64] http://fr.archive.ubuntu.com/ubuntu/ xenial-updates main universe
to do that, just
要做到这一点，只是
sudo nano /etc/apt/sources.list.d/*
and then close all the windows, except the ones with xenial-updateswhere you add universeat the end of the line!

You could also just do this:
你也可以这样做：
sudo add-apt-repository universe
sudo add-apt-repository universe
On older versions of Ubuntu, you might have to add a full deb source line:
在旧版本的 Ubuntu 上，您可能需要添加完整的 deb 源代码行：
sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) universe"
sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) universe"
After adding the repositories, do sudo apt-get updateto update the package list.
添加存储库后，请执行sudo apt-get update更新包列表。

check installed modules using; php -m in here you couldn't see mbstring module
Then check the php version php -v
Then install module using following command php5.6-mbstring
Restart the apache server service apache2 restart
使用检查安装的模块；php -m 在这里你看不到 mbstring 模块
然后检查php版本 php -v
然后使用以下命令安装模块 php5.6-mbstring
重启apache服务器服务apache2重启
finally thats work fine.
最后那工作正常。
