3. 解决办法

# 解决方法：
# 从报错来看是镜像仓库没有认证，不是安全的，可以通过 --allow-insecure-repositories 参数解决

# 以下为一般镜像仓库出问题的解决办法
1. 检查源是否正确，检查源的地址是否正确，检查源的类型是否正确；

2. 尝试更换源，更换源的方法可以参考Ubuntu官方文档；

3. 尝试更换源的类型，比如从http更换为https；

4. 尝试更换源的地址，比如从国内源更换为国外源；

5. 尝试更换源的更新方式，比如从apt-get更换为aptitude；

6. 尝试更换源的更新模式，比如从自动更新模式更换为手动更新模式；

7. 尝试更换源的更新模式，比如从自动更新模式更换为手动更新模式；

8. 尝试更换源的更新模式，比如从自动更新模式更换为手动更新模式；

9. 尝试更换源的更新模式，比如从自动更新模式更换为手动更新模式；

10. 尝试更换源的更新模式，比如从自动更新模式更换为手动更新模式；

11. 尝试更换源的更新模式，比如从自动更新模式更换为手动更新模式；

12. 尝试更换源的更新模式，比如从自动更新模式更换为手动更新模式；

13. 尝试更换源的更新模式，比如从自动更新模式更换为手动更新模式；

14. 尝试使用apt-get clean命令清理缓存；

15. 尝试使用apt-get update --allow-insecure-repositories命令允许更新不安全的源；

16. 尝试使用apt-get update --allow-unauthenticated命令允许更新不受信任的源；

17. 尝试使用apt-get update --allow-unauthenticated --allow-insecure-repositories命令允许更新不受信任和不安全的源；

18. 尝试使用apt-get update --allow-unauthenticated --allow-insecure-repositories --allow-releaseinfo-change命令允许更新不受信任、不安全和发行信息变更的源；

19. 尝试使用apt-get update --allow-unauthenticated --allow-insecure-repositories --allow-releaseinfo-change --allow-downgrades命令允许更新不受信任、不安全、发行信息变更和降级的源；

20. 尝试使用apt-get update --allow-unauthenticated --allow-insecure-repositories --allow-releaseinfo-change --allow-downgrades --allow-change-held-packages命令允许更新不受信任、不安全、发行信息变更、降级和更改已安装软件包的源。
