Since nknd v2.0.6, build nkn node from src code required Golang v1.13 or above.
We released a new mainnet version v2.0.6 at https://github.com/nknorg/nkn/releases . This version fixed the bug that caused block syncing fail at certain block. We recommend everyone to upgrade to avoid existing or future block syncing failure.
Starting from last version v2.0.5, minimal Golang version required is 1.13. If you are running old 1-click node from DO/GCP/AWS, you can ssh into the machine, copy and paste this line to terminal to upgrade Golang:
curl https://gist.githubusercontent.com…
We have updated the GCP Marketplace image. But DO/AWS Marketplace image packaged golang still v1.12. (A long time routine for audit)
For a workaround (before passed DO/AWS Marketplace audit), You can follow the upgrade guide in v2.0.6 release notes to upgrade Golang.
