I have been using the sns testing repo. I am trying to run this command on the live canister: ![image](https://us1.discourse-cdn.com/flex023/uploads/dfn/original/3X/6/9/69445a8e7aca8bf9c655fc3fd2d5965241a0f127.png) I just want to know why it fails as I can use that information to ensure dfx sns propose works without the same error, allowing me to confirm the sale will begin and plan around that. As for the testflight deploy I’ve tried multiple times, this command doesn’t work: ![image](https://us1.discourse-cdn.com/flex023/uploads/dfn/original/3X/9/d/9d6d6728b04ad4f3458030c2359d1df43a4b6336.png) so I get I need to installl sns-cli, which is different from the dfx sns library that contains the canister imports. Have you considered the response in this post that highlights issues with the sns testflight testing: > [@SNS testflight error](https://forum.dfinity.org/t/sns-testflight-error/27081/11): > > Hi everyone. There’s an issue still with using SNS testflight on mainnet and my top priority right now is to fix it and update the documentation. Once I do the experience will be a lot nicer. In the meantime, you can use these instructions to deploy a testflight to a local replica: First you need to get the right version of the sns binary, which this command will download to ./sns: GIT\_HASH="25d05cb2d7f3ec39541c825659199610e3fcea48" PLATFORM=$(uname | tr '[[:upper:]]' '[[:lower:]]') DOWNLOAD\_N… Have these been resolved now? --- _[View the full topic](https://forum.dfinity.org/t/add-nns-root-to-canister-fails/28040)._
