我尝试将系统从 ubuntu 18.04 升级到 20.04(在 HP Zbook 15u 上运行),但升级中断了。现在我无法正常启动 Ubuntu。你知道如何修复损坏的安装吗?
以下是更多详细信息:
- 我使用软件更新程序从 18.04 升级到 20.04 LTS。在“安装升级”阶段,系统关闭(首先屏幕冻结,然后变黑。
CRTL + ALT + F1
什么也没做,所以我唯一的选择就是重新启动系统)。 - 我尝试在恢复模式下启动(Grub 显示三个不同的内核:
Ubuntu, with Linux 5.4.0-77-generic
Ubuntu, with Linux 4.15.0-147-generic
Ubuntu, with Linux 4.15.0-135-generic
发生以下情况:
- 使用 5.4.0 我得到了内核崩溃
- 使用 4.15.0 版本我都可以进入安全模式
- 处于安全模式(使用 4.15.0 内核)
- 我运行了
dpkg
,但出现了错误 - 诸如此类的命令
apt-get update --fix-missing
提示我手动运行 dpkg,所以我这样做了:
- 我放下
root
并运行dpkg —configure -a
(按照其他帖子的建议)。然而,这并没有解决任何问题,我得到了以下输出

我听从了用户535733解决问题。因此,我创建了一个带有 Ubuntu 20.04 的可启动 USB,在 Try Out-Mode 下从它启动并备份了我的数据。然后我从 USB 重新安装了 Ubuntu 20.04。到目前为止效果很好。
因此,我遵循了以下说明:
