如何安装 Octave 4.2.0 或最新版本？我努力了：
- 当我已经安装了其他版本时安装最新版本的 GNU Octave: 没有给出 flathub 命令未找到
- 在 ubuntu 上从源代码安装 Octave 4.2.0？: 不起作用
- 在 ubuntu 上从源代码安装 Octave 4.2.0？：不起作用配置：
error: BLAS and LAPACK libraries are required - 在 ubuntu 上从源代码安装 Octave 4.2.0？: 不能工作安装4.0.3代替
这是我的电脑版本：
$ lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 9.6 (stretch)
Release: 9.6
Codename: stretch
我运行命令sudo -i进入root，然后运行以下命令。我不确定这是否正确。
$ sudo -i

您可以从以下位置安装 Octave 4.4.1（截至撰写本文时）：拉伸向后移植:
添加向后移植存储库（作为 root）
echo deb http://deb.debian.org/debian stretch-backports main > /etc/apt/sources.list.d/stretch-backports.list更新你的包索引
apt update安装 OpenJDK
apt install -t stretch-backports octave
如果您更愿意使用sudo，则等效步骤是
echo deb http://deb.debian.org/debian stretch-backports main | sudo tee /etc/apt/sources.list.d/stretch-backports.list
sudo apt update
sudo apt install -t stretch-backports octave
