Question

I want to fork the waves blockchain in which I wanted to change the coin. I first change the name of coin in waves node

link : https://github.com/wavesplatform/Waves/blob/version-1.2.x/node/src/main/scala/com/wavesplatform/transaction/assets/exchange/AssetPair.scala

according to the link I deployed on windows and I got this error.

ERROR: 18:28:45,568 ERROR [main] c.w.actor.RootActorSystem$ - Error while initializing actor system wavesplatform com.protonail.leveldb.jna.LevelDBException: IO error: /root/.local/share/waves-testnet/data: Invalid argument

(note : full error is given below)

software details:

1. openjdk11
2. ubuntu 18.04LTS

I am deploying in windows through ubuntu 18.04LTS by following steps for installing in windows and installing deb file.
