upon digging, my production.rb is owned by non-root 'ubuntu' who does not have write access to /tmp/passenger.1.0.747/generation-0/backends/ruby .

progressed, but still clueless how to fix it.

Workaround: So the problem was, capistrano deploy + passenger deploy as a non-root causes all these folder permission issues. had to revert to root deployment to workaround it

Solution

  • Issue was a non-root deploy via capistrano + standalone passenger. workaround: used a root deployment via capistrano, which solved the folder issue.
