Command to join channel (mentioned in instruction manual) :

Error: proposal failed (err: bad proposal response 500: cannot create ledger from genesis block: Expected block number=0, received block number=3)

Instead I tried below sequence of commands which worked fine & later commands to install & instantiate chaincode also but I need it to be verified to proceed confidently

Why in below command name for chaincode is mentioned twice, it looks wrong to me & also file sacc.go must be only sacc. Is it right..?
peer chaincode install -n ccForAll -v 1.1 -n networkChaincode -p github.com/sacc.go

garycris

This command doesn't make any sense to me either

peer chaincode install -n ccForAll -v 1.1 -n networkChaincode -p github.com/sacc.go

It appears like they are trying to make a copy of ccForAll and name it networkChaincode, but there is no reason given for this and it doesn't appear to work.

Lab7 is a complete mess and I have been trying to work my way through it multiple times. I thought I had it but then it blew up again in Lab8 so I am back again trying to work through 7. Currently having an issue upgrading the Chaincode (next step after the one you are on right now). First it errors because the version number is already in use so I tried reinstalling the chaincode with version 1.11. That worked but when I submit it for upgrade it tells me signature set does not satisfy the policy. I'm trying to do the upgrade from Org2.peer0, which is where I'm supposed to be. I can change to Org1 and I know it will work. It is not clear to me if that is the way it is supposed to be done or if it is supposed to work with Org2. I'm going back through other forum posts to try and figure it out.

Very frustrated and disappointed in the way this course has been put together. There are so many errors in the lab work it is nearly impossible to work through it. It's not that I can't figure out how to do it by doing it a different way based on documentation, but all the labs build on each other, so once you deviate the next lab doesn't work as expected.

Agreed @garycris, Lab 7 is a mess and it's frustrating.
I guess we've to keep trying & figure out on our own.

Yes, removing the .go from the end of that command seems to work for me. @abhishek thanks for the commands.

@LogarithmicTC @abhishek Correct, there is a typo in the commands, based on what the file name inside the container. I have forwarded the note to the course administrators.
