Failed to reach implicit threshold of 1 sub-policies, required 1 remaining : permission denied
While creating channel I have faced the same issue So there may be two resolution for that :
1] Either your previous network volume is not purged or deleted so just run the command docker volume prune and delete all the data in crypto-config and channel-artifacts folder.Follow the Hyperledger Fabric docs either create artifacts manually and start network or use byfn.sh.
This will resolve the issue if not then follow the second approach
2] Repository is not accessible(rd/wt permissions) so just give the access "sudo chmod 777 dir"
