Anyone have idea why it happen? Maybe it's a problem with rvm or something, I spent with this a lot of time but no success

Answer 1

• I also got the same issue like you (but my case is deploy to specific branch), and some one suggest here Capistrano error tar: This does not look like a tar archive . But he gave 2 options that should not suitable to my situation, I don't want to delete my current repo.
• So after 1 hour to workaround, I have a solution:

• Ex:

  • before: (deploy/production.rb)

     set :branch, ENV["BRANCH_NAME"] || "master" (I stay at master branch then run command) BRANCH_NAME=another_branch_name cap production deploy 

    then I get an error like above

  • after: (deploy/production.rb)

     set :branch, `git rev-parse --abbrev-ref HEAD`.chomp (I stay at another_branch_name then run command) cap production deploy 

    the error was fixed.
