y-ppa-manager not found some packages versions

[Flavio Antonini]

When I search for "grep" in y-ppa-manager I have found a version 3.1-2. Then, I search for "bash" and, in "savoury1/backports", I find "grep" in version 3.4... That latest version is not showed in first "grep" search. Therefore y-ppa-manager doesn't recognise all version for the same package.
The y-ppa-manager version:
 2020.01.30+1-1~webupd8~0.
My O.S. version:
 Distributor ID: Ubuntu
 Description: Ubuntu 16.04.6 LTS
 Release: 16.04
 Codename: xenial

Kind regards.

I tried to examine the issue. First of all I copied the "/usr/bin/y-ppa-search" script in my home directory:
  cp /usr/bin/y-ppa-search .
then I did the command to run the script in trace mode:
  sudo PS4='Line ${LINENO}: ' bash -x ./y-ppa-search
thence, after I inputed for searching "grep", I obtained the output trace and I discovered that script search for packages on following url:
  https://launchpad.net/ubuntu/+ppas?name_filter=grep
After that, I manually searched in browser, did cut & paste of above url and I discovered that ppa "savoury1/backports" (whit the alternative more recent "grep" version) isn't present in it. Therefore I suppose that the maintainer of this repository have forgot to reindexing the repository itself (if exist a similar procedure, I don't know).

Kind regards.
