这似乎是你的系统时间的问题。你的系统冻结时，存储库无效。看看这个回答服务器故障：

该问题似乎与有关clocksource，请检查 available_clocksource：

$ cat /sys/devices/system/clocksource/clocksource0/available_clocksource
tsc hpet acpi_pm

基于回答“clocksource tsc stable 是什么意思？” 看起来像TSC（时间戳计数器）不太可靠。

通过更新，/etc/default/grub您可以切换到另一个可用的时钟源。我正在使用高压聚酯。

GRUB_CMDLINE_LINUX_DEFAULT="clocksource=hpet"

并更新 grub：

update-grub2

重启后hwclock再次工作（不做任何修改就重启也可能有帮助 - 可能只是时间问题）。

笔记：最佳时钟源可能取决于您的主板和 CPU 型号。

因此，请按照以下步骤纠正你的时间：

  1. 使用文本编辑器以 root 身份进行编辑/etc/default/grub（例如sudo gedit /etc/default/grub：-）

  2. 找到该线GRUB_CMDLINE_LINUX_DEFAULT=""。

  3. 将该行改为如下形式：

    GRUB_CMDLINE_LINUX_DEFAULT="clocksource=hpet"

  4. 更新 grub：

    sudo update-grub

  5. 重启确认：

    sudo reboot

  6. 现在再次更新：

    sudo apt update

  7. 安装软件包：

    sudo apt install systemd-timesyncd
