It looks like this script fails when a dependency is found to be already installed. Instead of proceeding it halts. I'm not sure what would be the best way to go about that, but for my purposes I removed the exit in exitError() so that every command would at least be attempted and a log of failures were documented in stderr. Thank you for this awesome script!

Hey @mitchkm, I'm glad that you found it helpful! Yes, I made the script for the fresh installation purpose and yes, you just remove the exit 1 statement within exitError() function so that the script execution won't be stopped.

Thanks for the helpful blog post and script!

The mirror.centos.org ORBit2-2.14.17-6 links are now 404ing. Changing to the latest version, ORBit2-2.14.17-7, resolves it.

This change, along with hardcoding the current version in the path and @mitchkm's removal of the exit in exitError, are in this fork for Cypress 3.1.5:

Thanks @1083. Yes, the link is broken for Orbit2.2 (even yours too at this moment)!!. I think they all keep changing over the time (as of writing this, they're at this version). These are low level system dependencies to make the cypress work. You always have to test the script and have to make the fix if there are any glitches!
