Unfortunately, I don't know which version of pond this is (see https://github.com/agl/pond/issues/212).

This is a Google Chromebook Pixel 1, running Ubuntu.

I can't help with this specific tpm error. But if you want to compile a version without tpm support:

$ go get -tags notpm github.com/agl/pond/client

Have you done the usual tpm_takeownership1? This may be indicating that the SRK isn't set yet.

zookozcash commented 8 years ago

Thanks! I haven't done tpm_takeownership. I wasn't told to do when I followed these instructions: https://github.com/agl/pond

zookozcash commented 8 years ago

Sorry, I mean these instructions: https://pond.imperialviolet.org/

zookozcash commented 8 years ago

So… maybe the instructions should be updated to instruct people to do tpm_takeownership? And maybe the error message should be changed to instruct the user what to do or where to go for help? Or maybe instead pond should be changed to not require tpm?

zookozcash commented 8 years ago

Okay, I ran tpm_takeownership and afterward this error stopped happening and now pond starts normally. So, how about someone change it so that when this happens the error message says "Perhaps you need to run tpm_takeownership."? And someone change the instructions on https://pond.imperialviolet.org/ to tell people that they need to, or might need to, do this?

(Thanks, @Phoul.)
