E: Package ‘curl‘ has no installation candidate/ E:软件包没有可用的安装源

解决方案：

访问etc/apt/source.list 修改或者添加安装源

不用版本的Linux 有不同的配置比如我的是Debian 12

其他版本的去搜索引擎搜索即可

vim /etc/apt/source.list 改成修改或添加

// 以下是官方示例

deb http://deb.debian.org/debian bookworm main non-free-firmware
deb-src http://deb.debian.org/debian bookworm main non-free-firmware

deb http://deb.debian.org/debian-security/ bookworm-security main non-free-firmware
deb-src http://deb.debian.org/debian-security/ bookworm-security main non-free-firmware

deb http://deb.debian.org/debian bookworm-updates main non-free-firmware
deb-src http://deb.debian.org/debian bookworm-updates main non-free-firmware

最后更新下

apt-get update
