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。
