I am trying to build Tezos from sources, alphanet. When doing make build-deps here is the error I get:

[ERROR] The sources of the following couldn't be obtained, aborting:
      - hidapi.1.0-1: Bad checksum

I've been getting this since 2 or 3 days. Commands I tried:

sudo apt-get update
sudo apt-get dist-upgrade

git fetch origin
git reset --hard origin/alphanet
git clean -dxf

opam update
opam upgrade

But it's still giving me the same error. Any idea why?

  • This is the same problem as in the other question, and the same fix is now on alphanet branch.

  • @Tom yup, I've addressed the problem to Tezos gitlab earlier today. All good now! Commented Apr 12, 2019 at 19:42

The issue was the same in nature as in question

Error compiling tezos main net hidapi

But the patch had not been included on the alphanet branch. A ticket was raised


And the mainnet patch was cherry picked onto the alphanet branch


  • Thank you for all your help! :) Commented Apr 15, 2019 at 13:54
