Okay, I am going to do some testing. I will rerun the docs build for this PR and record the time it takes for each attempt.

1. 19m 35s
2. 8 min - then FAILED
3. 20m 19s
4. 17m 16s
5. 19m 33s
6. 53 m 51s
7. ?

Most recent one was 53 min. Was that with the --fix-missing? This is a really sad state of affairs! What is causing this wild variation with apt-get update?!

Yup, this was with --fix-missing.

I mean, I guess apt-get update and apt-get install are both slow and variable. But, the ARMI docs build needs to install pandoc and some latex stuff for the PDFs. Maybe I could try to install those manually, and that would solve the issue, I don't know.
