1. 问题：E: Package ‘curl’ has no installation candidate

Package curl 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 sourceE: Package 'curl' has no installation candidate

2. 解决

备份系统自带的源：

sudo cp /etc/apt/sources.list /etc/apt/sources.list.back

复制阿里或者清华源：

阿里源： https://opsx.alibaba.com/mirror
清华源：https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/
本人使用的是阿里源，以及是Ubuntu系统，ubuntu 18.04(bionic) 配置如下：

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

打开/etc/apt/sources.list文件，将原来的内容删除，然后将上述ubuntu 18.04(bionic)
的配置，粘贴上，保存：
```
sudo vi /etc/apt/sources.list
```
输入命令sudo apt-get update进行更新：
```
sudo apt-get update
```

最后，下载curl：

sudo apt-get install curl
