DigitalOcean droplets not installing ip-tables-persistent.

[WriteCodeEveryday]

Okay, this is going to sound crazy, but I just noticed this.

If you manually clear the .flynnrc file (we've been building clusters back and forth), and attempt to create a cluster on Digital Ocean, your installation will hang.

Logs below. Droplets have already been removed (and the removal process worked perfectly)

@WriteCodeEveryday the error seems to be:

E: Unable to locate package iptables-persistent

Can you try installing that package manually on one of the instances?

[WriteCodeEveryday]

@lmars Okay, so that package is not installable.

apt-get install -y iptables-persistent

Weird thing, if you "apt-get update" before attempting the install it does succeed.
Maybe there's a problem with the ppk that this package is hosted under?

The new droplets are now 16.04 droplets by default (maybe we need to update before install under 16.04 for that package?)

Still the case on fresh droplets.

Running sudo apt-get update before installing iptables-persistent worked for me
