W: GPG error: http://packages.ros.org/ros/ubuntu bionic InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY F42ED6FBAB17C654
这个错误是由于缺少ROS存储库的公钥导致的。你可以使用以下命令来解决这个问题:
```
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-key F42ED6FBAB17C654
```
运行以上命令将下载并安装ROS存储库的公钥。然后,再次尝试更新软件源和安装ROS:
```
sudo apt-get update
sudo apt-get install ros-melodic-desktop-full
```

这个错误是由于apt-key无法读取/etc/apt/trusted.gpg.d/目录下的文件,导致无法验证Ubuntu软件源的签名。解决这个问题的方法是:
1. 使用以下命令导入缺失的公钥:
```
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 871920D1991BC93C
```
注意替换上述命令中的871920D1991BC93C为您的错误中所提到的缺失的公钥。
2. 如果上述命令无效,可以尝试使用以下命令:
```
sudo apt-key adv --refresh-keys --keyserver keyserver.ubuntu.com
```
3. 如果上述命令仍然无效,可以尝试手动下载公钥并导入。首先,找到缺失的公钥的ID,例如871920D1991BC93C。然后,使用以下命令下载公钥:
```
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 871920D1991BC93C
```
最后,使用以下命令将公钥导入系统:
```
sudo apt-key add /path/to/downloaded/key
```
注意替换上述命令中的/path/to/downloaded/key为您下载的公钥文件的路径。
完成上述步骤后,再次运行apt-get update应该就不会出现上述错误了。
