I'm trying to update a diff and I run into this: $ arc diff Linting... LINT OKAY No lint problems. Running unit tests... No unit test engine is configured for this project. PUSH STAGING Pushing changes to staging area... sudo: a password is required fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists. STAGING FAILED Unable to push changes to the staging area. Usage Exception: Failed to push changes to staging area. Correct the issue, or use --skip-staging to skip this step. I believe that it worked for me before with my setup, and I seem to be in compliance with https://ghc.haskell.org/trac/ghc/wiki/Phabricator#Startingoff:Fixingabugsubm... Any ideas? Thanks, Bartosz
