Error installing php-db in Debian 10 Buster [Resolved]

I have been tried install php-db in Debian 10 Buster, which is a dependency required by PandoraFMS Console (I'm installing it) but not working to me.

when I try to install I lack the dependency:

dpkg: dependency problems prevent configuration of pandorafms-console:
   pandorafms-console depends on php-db; however:
      Package php-db is not installed.

And if I try to install php-db manually:

# apt install php-db
Package php-db is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'php-db' has no installation candidate

In I can search the package and I found that:

Package php-db

+ jessie (oldoldstable) (php): PHP PEAR Database Abstraction Layer
  1.7.14-3: all
+ stretch (oldstable) (php): Database Abstraction Layer
  1.9.2-1: all
+ sid (unstable) (php): Database Abstraction Layer
  1.9.2-2: all

For more information, the content of /etc/apt/sources.list is (obviated comments):

deb buster main
deb-src buster main

deb buster/updates main
deb-src buster/updates main
deb buster-updates main
deb-src buster-updates main

deb buster-backports main
deb-src buster-backports main

The directory /etc/apt/sources.list.d/ is empty.

What I can do?

I too face this problem of omitted packages, There are two ways to counter this,

1. You can download the specific missing package.

Now this something i really hate when i go for really stable system. This has potential to break your system if you're not fully aware of your doings.

2. You can add the repositry of last Debian distribution which had this package.

In your scenario its says that oldstable had that package,

 + stretch (oldstable) (php): Database Abstraction Layer
  1.9.2-1: all

Why don't you append old stable repositry, just add following to your /etc/apt/sources.list

deb oldstable main contrib non-free

Then just update and install like regular package.

sudo apt update && sudo apt install php-db && apt-mark hold php-db

But careful not to add unstable or testing repositries.
