这个错误提示是在从公钥服务器获取ROS的公钥时失败了。这可能是由于公钥服务器故障或网络连接问题引起的。您可以尝试以下解决方法:
1. 更换公钥服务器:尝试使用其它的公钥服务器,例如:keyserver.ubuntu.com。
```
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-key 421C365BD9FF1F717815A3895523BAEEB01FA116
```
2. 检查网络连接:确保您的网络连接正常,可以尝试使用ping命令测试公钥服务器是否可用。
如果以上方法仍然无法解决问题,您可以尝试等待一段时间,稍后再尝试执行该命令。

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。
