ubuntu16安装octave4.2.2(解决sudo: unable to execute /usr/bin/apt-add-repository: No such file or direct)

上一篇装完octave5.0.1结果没有GUI界面。。。。

4.0.0版本不稳定,会闪退,以下为正确安装过程4.2.2

首先移除已安装的所有版本的Octave

sudo apt-get remove octave

再安装octave

sudo apt-add-repository ppa:octave/stable
sudo apt-get update
sudo apt-get install octave

执行sudo apt-add-repository ppa:octave/stable时报错:

sudo apt-add-repository ppa:octave/stable sudo: unable to execute /usr/bin/apt-add-repository: No such file or directory 挂起

或者错误:

ModuleNotFoundError: No module named 'softwareproperties'

解决步骤:

(1)更换软件源:

中科大软件源镜像:

deb https://mirrors.ustc.edu.cn/ubuntu/ xenial main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ xenial main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ xenial-security main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ xenial-security main restricted universe multiverse

这个过程很长,中途会提示输入选项选择y就好。

(2)终端输入sudo apt-get install software-properties-common python-software-properties

(3)sudo ln -s /usr/local/bin/python3.5 /usr/local/bin/python3

sudo ln -s /usr/bin/python3.5 /usr/bin/python3

(4)sudo vim /usr/bin/add-apt-respository

将第一行的python3改成python3.5,因为之前的软连接操作已经将python3.5连接到python3了
