python-tornado is uninstallable from repo.saltstack.com

[rvandegrift]

Salt cannot be installed from the ubuntu trusty saltstack repo due to a bad python-tornado package:

ubuntu@ubuntu:~$ apt-cache policy python-tornado

The source package http://repo.saltstack.com/apt/ubuntu/14.04/amd64/latest/python-tornado_4.2.1-1.dsc builds an installable package - perhaps there's some corruption in the repo?

@rvandegrift, thanks for reporting. Ping @dmurphy18.

@rvandegrift I just tried to install python-tornado on a clean Ubuntu 14.04 machine with apt-get and aptitude without error for

root@david-VirtualBox:/home/david# apt-cache policy python-tornado
python-tornado:
Installed: (none)
Candidate: 4.2.1-1
Version table:
4.2.1-1 0

Can you retry the operation but first re-run apt-get update and check that the key for repo.saltstack.com is installed correctly and there are no errors in accessing repo.saltstack.com during apt-get update.

You are correct! I think I've found an apt-cacher-ng bug. Not sure why it's involved - I don't cache for repo.saltstack.com. Sorry for the spurious report!

@rvandegrift, no problem. Thanks for your research.
