安装Sagemath时的问题

Question

在Ubuntu 20.04中，当我键入：

sudo apt-get install sagemath sagemath-jupyter sagemath-doc-en

我得到：

Package sagemath 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 'sagemath' has no installation candidate
E: Unable to locate package sagemath-jupyter
E: Unable to locate package sagemath-doc-en''

看来PPA不再被维护了。是我被迫经历了获取二进制和所有依赖项的麻烦，还是遗漏了一些显而易见的东西？我觉得自己很蠢。

在添加宇宙存储库并再次安装之后，我得到：

E: Package 'sagemath' has no installation candidate

在添加宇宙存储库并再次安装之后，我得到：

E：'sagemath‘软件包没有安装候选

与从Ubuntu存储库安装不同，您可能会发现更容易转到https://www.sagemath.org/download.html并直接下载当前版本。安装很简单。我建议将文件解压缩到一个目录~/Sage，cd ~/Sage/SageMath，然后执行./sage

几分钟后，一切都安排好了。目前版本9.2有二进制文件，但9.3应该很快就会出现。
