无法在18.04以下安装全文本或文本xetex

Question

在升级到18.04之后，我清除了以前版本的所有文本记录，但是现在我不能安装texlive、texlive满或者texlive-xetex。

例如，sudo apt install texlive给了我一个消息：

 Package texlive is not available, but is referred to by another package.
 This may mean that the package is missing, has been obsoleted, or
 is only available from another source
 E: Package 'texlive' has no installation candidate

同样的，sudo apt-cache policy texlive给了我

 texlive
    Installed: (none)
    Candidate: (none)
    Version table:

我可以安装texlive-base，但是我需要texlive-xetex

Answer 1

按照下面的说明为我做了个窍门：

sudo add-apt-repository universe
sudo apt update
sudo apt install texlive-xetex
