无法设置IP表:无法启用NAT规则

我正在做这个教程: https://hyperledger.github.io/composer/latest/installing/development-tools

现在我想从 ./startFabric.sh 但是我得到了一个错误:

dany@DESKTOP-IQB2P0B:~/fabric-dev-servers$ ./startFabric.sh
Development only script for Hyperledger Fabric control
Running 'startFabric.sh'
FABRIC_VERSION is set to 'hlfv12'
FABRIC_START_TIMEOUT is unset, assuming 15 (seconds)
Removing network composer_default
