This seems like an issue with your system time. The repository wasn't valid at the time your system is frozen on. Take a look at this answer on Server fault:

The problem seems to be connected to clocksource, check available_clocksource:

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

Based on answer to "What does “clocksource tsc unstable” mean?" it looks like TSC (Time Stamp Counter) is not very reliable.

By updating /etc/default/grub you can switch to another available clocksource. I'm using HPET.

GRUB_CMDLINE_LINUX_DEFAULT="clocksource=hpet"

and updating grub:

update-grub2

After reboot hwclock works again (just reboot without any modification might have helped as well - it might be just question for how long).

NOTE: Optimal clocksource might depend on your motherboard and CPU model.

So, follow these steps to correct your time:

  1. Edit /etc/default/grub as root using a text editor (eg:- sudo gedit /etc/default/grub)

  2. Locate the line GRUB_CMDLINE_LINUX_DEFAULT="".

  3. Change the line to look like:

    GRUB_CMDLINE_LINUX_DEFAULT="clocksource=hpet"

  4. Update grub:

    sudo update-grub

  5. Reboot to confirm:

    sudo reboot

  6. Now update again:

    sudo apt update

  7. Install the package:

    sudo apt install systemd-timesyncd
