No Release File

[bsmither]

Where is the Bionic repo?

If you are referring to the default repository for all things Linux Mint,
there was only Nginx 1.14.

Anyway, as is always the case, something went wrong. I don't have a
'modules-available' directory, and all the items in 'modules-enabled' end in
'.removed' with link (broken).

Curses.
