Intermittent internet loss causes downloads to hang indefinitely

[gmertes]

I have unstable internet, and every so often my internet will disconnect for a second or two. When this happens right in the middle of a package download, the download will stall and hang indefinitely. The progress bar gets stuck and it will not recover by itself when connectivity is restored (ctrl+c also does nothing). The only solution is killing the process and restarting.

Is there a way to detect loss of connectivity during a transfer, or can we set a maximum time that a transfer is allowed to take before it kills itself and tries again? The current retry mechanic does not do anything for these kind of mid-download disconnects.

Potentially found the cause of the problem and submitted fix PR. Currently testing if this is the definite cause, but a socket timeout is consistent with the issue.

EDIT: I've confirmed that adding the timeout fixes my issue. I'm now seeing requests.exceptions.ReadTimeout exceptions causing the download to retry instead of hanging indefinitely.
