The issue preventing NavPi users from successfully upgrading to 4.2.0 has now been patched with version 4.2.1. If you are using the NavPi and want to support the community fund accumulation soft fork make sure you update now and resume staking with the new version.

Release Notes

The wallet will try to synchronize clock every 30 seconds on launch until it succeds instead of just checking once and exiting if it fails.

Enforces 32-bit data type for the buffer when reading from the NTP Server socket, fixing some compatibiity issues with 32-bit systems like Raspberry Pi.

Reduce NTP connection timeout to 5 seconds.
