我正在使用“termux”（android 终端模拟器）。我最近在“proot”环境中安装了 Ubuntu。当我使用 'apt search Octave' 搜索八度包时，我找不到任何结果。然后我在Ubuntu软件包中手动搜索octave来验证它是否可用于'armhf'。令我惊讶的是它可用于 'armhf' 。我真的很想在我的 android 上使用八度。为什么它没有出现在 apt 搜索中？我能做什么来修复它？
Ubuntu 包搜索：https://packages.ubuntu.com/search?suite=artful&arch=armhf&searchon=names&keywords=Octave
“cat /etc/apt/sources.list”的输出

答案1
这octave软件包可在universe存储库中找到：
sudo add-apt-repository universe
sudo apt update
sudo apt install octave
您应该能够通过向您的
/etc/apt/sources.list文件中添加一行来使用列出的任何镜像，如下所示：
deb http:// artful main universe
对于您的情况，只需执行以下操作：将第三行更改为：
deb http://ports.ubuntu.com/ubuntu-ports/ artful main universe restricted
然后更新你的系统。
