when I try to build my network, I just copy the byfn sample files, but it doesn't work for me. I even don't change a word. So how can I fix it? Config update for existing channel did not pass initial checks:

implicit policy evaluation failed - 0 sub-policies were satisfied, but this policy requires 1 of the 'Writers' sub-policies to be satisfied: permission denied

  • Can you specify the versions of Fabric, the Samples and client binaries you are using. (Sometimes you see this error with mis-matched versions.) – R Thatcher Dec 24 '19 at 09:43
  • I have the same problem, I am on HL Fabric 1.4.4 ( 1.4.4 /1.4.4 / 0.4.18 ) – Juliatzin Feb 19 '20 at 08:50

This error is probably due to the wrong certificates of identities used while submitting the request. Eg: while creating channel. Follow this SO post When I try to create a channel using Hyperledger Fabric, the request fails

For a quick workaround you can restart the network by creating new set of crypto material if you're not sure about which exact identity is creating the problem. Don't forget to do a docker network prune and docker volume prune before restarting.
