I am about to install postfix/Dovecot in Redhat Linux server. After checking this link http://www.linuxfromscratch.org/blfs/view/svn/server/postfix.html, I knew that I had to install berkley database too.
But after checking softwares installed on the server, I found another DB SW installed.
Can I depend on another kind of databases other than the one required in the above link?

You don't mention the version of Red Hat, but I assume you use a version which is not so terribly old it does not have yum.
With
yum deplist postfix
you can list all the dependencies which postfix has in the RPM package. On my Fedora system, libdb is listed as a dependency, which is the Berkeley DB library and is sufficient for postfix.
When you install RPM's with yum, the dependencies are automatically resolved and everything which is required will be installed. Trust yum.

Is there apt-get install analog command in Buildroot? I want to install some applicatin but how?
From documentation of BuildRoot:
Buildroot is not meant to be a distribution
(or rather, a distribution generator.) It is the opinion of most
Buildroot developers that this is not a goal we should pursue.
We prefer to push Buildroot in a direction that makes it easy
(or even easier) to generate complete root filesystems. This is what
makes Buildroot stands out in the crowd (among other things, of
course!) We believe that for most embedded Linux systems, binary
packages are not necessary, and potentially harmful.
So, It seems No! you can not do that by using apt. you need to directly add your packages based on documentation
By default in LINUX/UBUNTU Operating system is having apt-get installed so you can directly start using sudo apt-get install [Package Name that you want to install]

I have installed the latest stable version of Ubuntu (Ubuntu 18.04.4 LTS).
I remarked that when I search for library like "Eigen or openMp", I have no result. However, in older Ubuntu versions, I could install lot of libraries. I know that I can install them via terminal, but I prefer to find them via the software-center. Is there a trick to let the software-center find such libraries ?
Some libraries receive updates to support latest ubuntu versions after a considerable period of time.What you can do is downloading the debian package from internet and install it using Ubuntu Software Manager.Visit the link below for more details.

When I run yum update, it lists the packages that it will upgrade. For one of the packages, kernel, it lists it under the "Installing" header. All other packages are listed under the "Upgrading" header. Why does it say that is "Installing" that package? The current version of that package is 4.14.104-95.84.amzn2 and it will be upgraded/installed to 4.14.114-103.97.amzn2. This is not even a major version change, in which case, it might have made sense. Is there a general case where this happens? Or is this only specific to kernel and related packages, since they are special in a sense?
From here - https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8-beta/html/managing_monitoring_and_updating_the_kernel/updating-kernel-with-yum_managing-monitoring-and-updating-the-kernel
The yum package manager always installs a new kernel instead of replacing the current one, which could potentially leave your system unbootable.
The system must be rebooted after installing kernel package for consistency, integrity reasons.
Also yum handles updating the kernel package so that end-user need not worry about upgrading or installing it.

I've received a linux-yocto box. I now I'm trying to installing some software, on ubuntu I use apt-get but it seems not to work/installe. so I've tried yum same result.
so my question is, is there a way to find out which package manager is install on my linux system ?
thanks in advance !
Yocto is using either rpm, dpkg, or opkg as the package manager. If the tools are installed on the image, which isn't a requirement, then the binaries are either dnf (or yum if it is a really old release), apt-get, or opkg respectively.
There's a reasonable chance that you've been given an image without a package manager or a working feed though. The joy of Yocto is that it is so flexible, so you should ask whoever gave you the software.

What command do I run in order to update firefox using rpm?
I have been asked this question and am not aware how to do it. Any help will be appreciated.
You perhaps could do this using your distro's software updater, but suppose you've got FF's installer (rpm) file and also suppose that it's called firefox.rpm. You should then do:
rpm -Uvh firefox.rpm
If you don't have any previous FF version installed on your computer you might as well do:
rpm -ivh firefox.rpm
Alternatively, if you have yum configured on rpm based systems (RHEL or Fedora) you could simple run the below command, this would download and update the dependencies, instead of just updating only a single firefox rpm.
`yum update firefox`
