在Ubuntu 18.04中打包php7.2-mbstring unmet依赖项
尝试为mediawiki安装程序安装php-mbstring 。
在第一次尝试Universe存储库后添加： 在Ubuntu 18.04中缺少软件包php7.2-mbstring
但是给我带来的困难在这里详情：

您缺少sources.list一些必要频道。 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
您知道的包裹信息已过期。
使用rmadison工具，我们可以在repos中看到php7.2-mbstring所有版本：
php7.2-mbstring | 7.2.3-1ubuntu1 | bionic/universe | amd64, arm64, armhf, i386, ppc64el, s390x php7.2-mbstring | 7.2.7-0ubuntu0.18.04.2 | bionic-security/universe | amd64, arm64, armhf, i386, ppc64el, s390x php7.2-mbstring | 7.2.7-0ubuntu0.18.04.2 | bionic-updates/universe | amd64, arm64, armhf, i386, ppc64el, s390x
虽然我只在这里展示Bionic项目。
因为您的系统不知道安全性或更新repos中的较新的php7.2-mbstring ，所以您的版本不匹配。
运行这个：
sudo apt-get update sudo apt-get upgrade sudo apt-get install php7.2-mbstring
这应该有助于将您的版本恢复到他们需要的位置。 （注意，您可能希望使用dist-upgrade而不是upgrade以便更新的内核包等软件包也得到安装和升级）
