Comment 5 for bug 1744758

Since archives of Zesty are gone this is hard, you can't install packages anymore you don't have yet. The closest are Artful and Xenial.
But Lee already tested 3.6 which is more or less what is in Artful.

There is quite a chance that this is related to the gnutls FTBFS we had in zesty, as I outlined in comment #1 - but the build itself looks good.

Maybe it is time to let the CI move up to a supported repo.
@Corey - does UCA-O still have support far longer than Zesty that is EOL now?
@Corey - you might need to drill down the Ocata build or use ddebs from UCA to step through the function if the ecnryption support is really missing.
