因此，我尝试了这个：

在 Ubuntu 16.04 上执行命令 sudo apt-get update 后出现以下错误 - 代码日志但没用。然后我尝试“sudo apt-get update” 的多个问题 - Ubuntu 论坛

这意味着，当我尝试通过软件更新工具（银色圆圈图标）将 dist 从 16 升级到 18 时，我会得到这个：在 Ubuntu 16.04 上执行命令 sudo apt-get update 后出现以下错误 - 代码日志

答案1

您当前正在运行版本 16.10 (雅克蒂雅克)，即标准版本达到生命尽头2017 年 7 月。标准版本每 6 个月发布一次，升级周期较快：仅支持 9 个月。预计此升级周期的用户将在新版本发布后 3 个月内升级。

相比之下，LTS（长期支持）版本，例如 16.04.6（赛尼尔·赛鲁斯），每两年发布一次，并支持至少5年。

看发布 - Ubuntu 维基以获取完整的发布列表和支持日期。

你收到错误的原因是apt因为apt尝试获取更新的软件包雅克蒂雅克，但大多数镜像不再托管该版本 Ubuntu 的任何内容。相反，所有软件包信息都已移至旧版本。

您仍然可以使用 Live CD 或可启动 USB 映像您要升级到的版本。应该有一个选项升级在安装过程中分配驱动器空间“ 迅速的。

截至本答复，最新的标准版本是 19.04，将支持到 2020 年 1 月。最新的 LTS 版本是 18.04.2，将获得支持到 2023 年 4 月，并且 Canonical 将额外提供五年的延长安全维护 (ESM) 到 2028 年。
