我在终端中执行以下命令时意外丢失了一些系统文件：
sudo apt-get purge wine\*
大多数已安装的软件（终端、软件中心、libreoffice 等）现在都丢失了。
有人能解决这个问题吗？
答案1
以下是已删除软件包的列表（至少在 Debian 上）：
➜ ~ apt-get -s purge wine\*
NOTE: This is only a simulation!
apt-get needs root privileges for real execution.
Keep also in mind that locking is deactivated,
so don't depend on the relevance to the real current situation!

被删除的最可怕的软件包是x-window-manager，但实际上并没有被删除。我可以说的是，除非您使用 KDE 或 MATE，否则没有任何软件包的删除会导致您的系统软件包被删除，或使您的系统瘫痪，事实上，如果有任何真正重要的软件包会导致您的系统处于无法启动的状态，您应该会看到类似这样的警告：
WARNING: The following essential packages will be removed.
This should NOT be done unless you know exactly what you are doing!
apt
在这种情况下，它会要求您输入完整的短语“我知道我在做什么！”，字面意思。因此，由于我们知道哪些软件包被删除了，我们可以知道我们失去了哪些功能……事实上什么功能都没有！我们仍然有 network-manager 和 apt/dpkg，因此修复/恢复这个问题将轻而易举，只需移动到 TTY（++ Ctrl）并安装元软件包就足以让一切恢复正常。AltF1(k|l|x)ubuntu-desktop
sudo apt-get install ubuntu-desktop
从那时起，检查您安装的其他软件包是否不再安装。
啊，最后的忠告，除非你知道正则表达式会做什么，否则不要这么做。它匹配任何名称中包含win或的包wine。并且一如既往-s，/--simulate是你的朋友。
