'python-software-properties' 在安装 Torch 时没有安装候选

Question

我正在使用 Ubuntu 并想安装 Torch。我正在遵循本指南。

第一行运行良好：

git clone https://github.com/torch/distro.git ~/torch --recursive

但是失败了

cd ~/torch; bash install-deps;

Package python-software-properties is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  software-properties-common

E: Package 'python-software-properties' has no installation candidate

(Had to add spaces to the links because I don't have enough rep)

**dpkg -L python-software-properties | xargs ls -d > /dev/null** yields

dpkg-query: package 'python-software-properties' is not installed
Use dpkg --info (= dpkg-deb --info) to examine archive files,
and dpkg --contents (= dpkg-deb --contents) to list their contents.

此命令给出相同的错误消息：

sudo apt-get install --reinstall python-software-properties

我跑了sudo apt-get install software-properties-common，它安装得很好，但我仍然遇到同样的错误。

我正在通过 USB 64 位运行最新版本的 Ubuntu

Answer 1

问题出在脚本中install-deps

请将第 139 行替换为以下命令。

sudo apt-get install -y software-properties-common
