I have already installed and worked in hyperledger fabric in ubuntu 16.04 and somehow i deleted the packages. I want to reinstall it again and working but it always showing up the error in first-network itself.

So can anyone suggest me how to start over it from the first?

  • just ./byfn down and up. What are you missing exactly? Fabric samples? – Riki95 Feb 07 '20 at 08:35
  • Yes i have tried. But while doing ./byfn up, I am receiving error like this got unexpected status: BAD_REQUEST -- error applying config update to existing channel 'mychannel': error authorizing update: error validating ReadSet: proposed update requires that key [Group] /Channel/Application/Org1MSP be at version 0, but it is currently at version 1. I have cleared docker images and tried, nothing works. How to resolve this? – divya sekaran Feb 07 '20 at 08:51
  • Appears that your previous data was not deleted. Did you run `./byfn down` first? – Gari Singh Feb 07 '20 at 09:05
  • Yes I did, and it shows ---- No containers available for deletion ---- ---- No images available for deletion ---- – divya sekaran Feb 07 '20 at 09:12
  • I tried removing all containers and images, and start all over again. while running ./byfn up, getting error like Error: error getting chaincode bytes: failed to calculate dependencies: incomplete package: github.com/hyperledger/fabric-chaincode-go/shim. How to resolve this. – divya sekaran Feb 07 '20 at 10:19

Make sure you add the go.mod and go.sum for the vendored packages, chaincode in 2.0.0 does not include the packages, follow the chaincode structure of go.mod and go.sum like here

https://github.com/hyperledger/fabric-samples/tree/master/chaincode/marbles02/go

, then execute the following command to vendor the packages,

go mod download

try pruning the docker volumes and system. Use docker volume prune -f and docker system prune -f

  • Tried this. Though getting the same error "Error: error getting chaincode bytes: failed to calculate dependencies: incomplete package: github.com/hyperledger/fabric-chaincode-go/shim" – divya sekaran Feb 10 '20 at 06:21
  • `go get github.com/hyperledger/fabric-chaincode-go/shim`. Assuming you have set GOPATH correctly. – Aditya Arora Feb 10 '20 at 06:27
