无法在 ubuntu 18.04 LTS 上安装 sagemath

最近，我安装了 Ubuntu 64amd，并与 Windows 7 32 位进行双重启动。一切正常，但我无法在其中安装 sagemath。即使代码正确，它仍显示“无法找到软件包 sagemath-upstream-binary”。我可以知道原因吗？

以下是我使用的完整代码：

sudo apt-add-repository -y ppa:aims/sagemath
sudo apt-get update
sudo apt-get install sagemath-upstream-binary

以下是终端代码：

答案1

这您提到的 PPA没有适用于 18.04 LTS 的软件包。

以 Ubuntu 18.04 LTS Bionic Beaver 为例你不需要任何 PPA安装 SageMath。

您可以简单地删除 PPA（如果之前添加了）：

sudo apt-add-repository -r ppa:aims/sagemath

然后从存储库安装 sagemath：

sudo apt-get install sagemath
