Answer 1

您缺少一些来自sources.list. 做sudo gedit /etc/apt/sources.list并让它看起来像这样：

deb http://archive.ubuntu.com/ubuntu bionic main multiverse restricted universe
deb http://archive.ubuntu.com/ubuntu bionic-security main multiverse restricted universe
deb http://archive.ubuntu.com/ubuntu bionic-updates main multiverse restricted universe

保存并退出。然后更新您的存储库：

sudo apt update

然后安装php-mbstring：

sudo apt install php7.2-mbstring
