Error: 'os-agent_1.5.1_linux_x86_64.deb' is not a Debian format archive - corrupted downloads?

Hi, I’m confused by a problem I’m having trying to install the OS Agent. This manifested itself as the “not a Debian format archive” error shown at the bottom of this post. But the actual issue is that the downloads seem to be corrupt every time.

In the command sequence below, you can see that 2 different downloads result in files with different checksums; neither being the right one. Given I’ve tried this on two different machines at my end I’m thinking that whatever is serving these files is messed up?

Or have I missed something?

I’ve also tried downloading older versions of the agent, and get exactly the same problem.
