Melpa package Ebib does not appear on the package list

Question

I'd like to install the Ebib package, whose official homepage is: https://joostkremers.github.io/ebib/. According to the Installation section on this homepage,

The easiest way to install Ebib is to use Melpa.

So I installed Melpa by following the instructions given in the Installing Melpa section of the following page: https://melpa.org/#/getting-started

I restarted Emacs, and executed M-x package-list-packages. The resulting list included packages for which melpa was specified in the Archive column. However, the package ebib was not on the list.

How can I install the Ebib package?

Answer 1

After closing and opening Emacs a few times, and executing M-x package-list-packages every time, the Ebib package eventually appeared. Then it disappeared again. Then reappeared. Executing M-x package-refresh-contents didn't make things more predictable. But the point is, eventually the "missing" appeared.
