These are the steps I took:

  1. open https://suite.trezor.io/

  2. download the 3 files: Desktop app, signature and signing key

  3. follow the instructions https://wiki.trezor.io/Apps:Trezor_Suite#How_to_run, How to verify the binaries,2 terminal commands.

Question: Can I still trust the Suite?


1 Answer 1


Question: Can I still trust the Suite?

Yes. GPG indicates that there is a valid signature for SatoshiLab's signing key.

GPG has a thing called the "trust database" (trustdb). This is a local database of keys that you have told GPG that you trust, with trust meaning that you have verified that the owner of that key is who the key says it belongs to. By default, keys are not trusted or have an unknown trust value as you have to verify the identity externally, and then inform GPG.

So the warning that you see is simply GPG telling you that this particular key does not have a trusted value in the trustdb. You have not told GPG that you trust this key, and it is merely reminding you of this fact.

  • Thank you for the answer. I'd recommend Satoshi Labs to include this information in their instructions so newbies don't panic :)
