你可以按照以下步骤在 Ubuntu 20.04 中添加 DNS：

1. 打开 /etc/netplan 配置目录，使用以下命令：

   sudo nano /etc/netplan/00-installer-config.yaml

2. 在 "ethernets" 部分下添加以下内容：

   nameservers:
       addresses: [8.8.8.8, 8.8.4.4]  # 在此处添加你的 DNS 服务器地址

请注意，这里使用的是 Google 的 DNS 服务器地址，你可以将其替换为你所使用的 DNS 服务器地址。

3. 保存文件并退出。

4. 使用以下命令更新网络配置：

   sudo netplan apply

5. 确认 DNS 是否正确配置。使用以下命令检查 DNS 配置：

   cat /etc/resolv.conf

如果看到正确的 DNS 服务器地址，则说明配置成功。

希望这可以帮助你在 Ubuntu 20.04 中添加 DNS。

grpc版本是1.33.2；protoc版本是3.13.0 官网对应的 编译报错： #error: This file was generated by a newer version of protoc which is

incompatible with your Protocol Buffer headers. This error occurs when the version of protoc that was used to generate the .pb files is newer than the version of protoc that is installed on your system.

To solve this issue, you can try upgrading your version of protoc to match the version that was used to generate the .pb files. Alternatively, you can regenerate the .pb files using the version of protoc that is installed on your system.

To regenerate the .pb files, you can use the following command:

protoc --grpc_out=. --plugin=protoc-gen-grpc=/usr/local/bin/grpc_cpp_plugin --cpp_out=. your_proto_file.proto

Replace `your_proto_file.proto` with the name of your .proto file, and `/usr/local/bin/grpc_cpp_plugin` with the path to your `grpc_cpp_plugin` binary.

这段话是由Qt的用户界面设计器生成的Python代码的注释，它告诉我们这个代码文件是从一个名为"login.ui"的Qt用户界面文件生成的，并且这个文件是由PyQt5的UI代码生成器（pyuic5）生成的。这段话还提醒我们，如果我们手动修改这个文件，那么在下一次运行pyuic5时，我们的修改将会被覆盖掉。因此，我们应该避免手动修改这个文件，除非我们非常清楚我们在做什么。
