无法在ubuntu 18.04 LTS上安装sagemath
最近，我安装了Ubuntu 64amd，使用Windows 7 32bit进行duak启动。 一切都很好，但我无法在其中安装sagemath。 它说“无法找到包sagemath-upstream-binary”，即使代码是正确的。 我可以知道为什么吗？
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：
kutubuddin@kutubuddin-h81m-s:~$ sudo apt-add-repository -y ppa:aims/sagemath [sudo] password for kutubuddin: Ign:1 http://ppa.launchpad.net/aims/sagemath/ubuntu bionic InRelease Get:2 http://security.ubuntu.com/ubuntu bionic-security InRelease [69.9 kB] Err:3 http://ppa.launchpad.net/aims/sagemath/ubuntu bionic Release 404 Not Found [IP: 91.189.xx.xx xx] Hit:4 http://in.archive.ubuntu.com/ubuntu bionic InRelease Hit:5 http://in.archive.ubuntu.com/ubuntu bionic-updates InRelease Hit:6 http://in.archive.ubuntu.com/ubuntu bionic-backports InRelease Reading package lists...

您提到的PPA没有18.04 LTS的包装。
对于Ubuntu 18.04 LTS Bionic Beaver， 您不需要任何PPA来安装SageMath。
您可以简单地删除PPA（如果之前添加）：
sudo apt-add-repository -r ppa:aims/sagemath
然后从存储库安装sagemath：
sudo apt-get install sagemath
