最近在编译Armbian时候遇到**“the following signatures couldn’t be verified because the public key is not available”**

```shell

lbl@orangepi4:~$

```

### 原因：

这个问题在使用`apt-get update`就会出现，Ubuntu 环境下，也会出现这个情况，出现这个问题的原因是：**apt打包系统具有一组受信任的密钥，这些密钥确定软件包是否可以通过身份验证并因此受信任以安装在系统上。但是有时候系统并没有所需的所有密钥，因此会遇到此问题。**

如果不解决这个问题，那么在使用`sudo apt-get upgrade`时就会遇到错误而无法更新。

```shell
lbl@orangepi4:~$ sudo apt-get upgrade
Reading package lists... Done
Building dependency tree... Done
Calculating upgrade... Done
...
E: Some packages could not be authenticated
lbl@orangepi4:~$
```

### 解决办法：
只需要将出现`NO_PUBLIC`添加进到系统即可，将最后出现的一串`KEY` 通过以下命令添加到系统中。如我上面最后出现的一串`NO_PUBKEY 7638D0442B90D010 NO_PUBKEY 04EE7237B7D453EC NO_PUBKEY EF0F382A1A7B6500`
这里共有3个，所以要添加三次，使用下面命令

```shell
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 7638D0442B90D010
```

```shell
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 04EE7237B7D453EC
```

```shell
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys EF0F382A1A7B6500
```
每个密钥只需要添加一次就可以，添加成功标志：

```shell
lbl@orangepi4:~$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 7638D0442B90D010
Executing: /tmp/apt-key-gpghome.pDTXaMVLxm/gpg.1.sh --keyserver keyserver.ubuntu.com --recv-keys 7638D0442B90D010
gpg: key 7638D0442B90D010: 14 signatures not checked due to missing keys
gpg: key 7638D0442B90D010: public key "Debian Archive Automatic Signing Key (8/jessie) <ftpmaster@debian.org>" imported
gpg: Total number processed: 1
gpg:               imported: 1

```

至此，密钥已经添加成功，试试

```shell
sudo apt-get update
sudo apt-get upgrade
```

    阿里云比较坑，机器性能没有100%，1M的带宽必须要配合CDN 使用，加载速度才有保证
