Issue with Linux Mint 21.3: unable to fetch all repository indexes
I just upgraded using the GUI upgrade tool to Linux Mint 21.3 MATE. I'm encountering an error when refreshing updates. The system says the repository might be unavailable due to network issues, and if so, it will fall back to an older version. Please check your internet connection and confirm the repository address in your settings. The release file link isn't working yet, and updates won't apply until the delay ends.
Your system clock is misaligned. I experienced the same problem before. Ensure your PC remains powered on continuously to prevent the CMOS battery from depleting, and think about installing NTPd or a similar tool to handle and correct the clock if needed. Chrony, when configured with an rtcdrift file, will synchronize with the clock drift after a reboot. It requires command-line interaction and may take time to resolve, but it helps prevent these minor complications. The archwiki offers excellent examples of setting up chrony using an rtcdrift file if you wish to configure it.
Consider chrony for a more precise clock that adapts to RTC drift without daily updates. Set it up via a config file addition to monitor drift and maintain accuracy with fewer server syncs. The arch wiki provides an example: https://wiki.archlinux.org/title/Chrony Using the rtcfile setup in /etc/chrony.conf ensures stability after reboots. Initially, the system syncs to a time server post-reboot, calculates drift, and adjusts accordingly. Previously, I faced a minute discrepancy but no backward drift. Now, with rtcfile enabled, daily or weekly updates are unnecessary, benefiting logs and error records during restarts.
