As it is visible in the screenshot, I did not get a green tick in the "setting up box". And I feel due to which cd client && npm run start not working. Please tell how to resolve this.
I was able to
truffle unbox zeppelinos/zepkit though on Windows Subsystem for Linux on my laptop it took a while (4-5 minutes).
I see that you raised this as an issue in GitHub where the advice was to use
zos unpack tutorial that you did successfully using the current version of zos.
If you have more questions about ZepKit you can always ask in the community forum
