apt-get upgrade arvados-api-server on Ubuntu 12.04 did not update crunch-job
My jobs were failing since I upgraded docker to 1.13.1 and installed v1.10+ versions of the docker images in keep.
They were giving the error:
No Docker image hash found from locator e829be6274c110c4c16bf6381efae022+594 at /var/www/arvados-api/shared/vendor_bundle/ruby/2.1.0/gems/arvados-cli-0.1.20161017193526/bin/crunch-job line 413
Note the date/version of the arvados-cli gem was rather old. I ran `bundle update arvados-cli` in /var/www/arvados-api/current which installed the new crunch job and fixed the problem.
My expectation would have been that the crunch-job script in the api server bundle would have been updated when I did the apt-get upgrade, but for some reason it was not.
