Hi All,
I want that my all ubuntu system should update or even install there packages in my Cent_os server Through yum repository. How'z it worked.

If I understand what you are asking correctly, you cannot install the packages from the Cent OS via yum on Ubuntu. Yum is the tool used for distros that use RPM. Ubuntu uses tools like apt-get and aptitude to install .deb packages. You are welcome to convert RPM packages to DEB packages or just find the equivalent package you want (i.e there is a RPM package you want ... find the same package in deb format). Alternatively, you can always build from source. Good luck.

Yea as wesaus32 stated, those are two completely different package managers. Packages from yum are not compatible with the apt-get manager and vise versa.

Take a look here http://how-to.linuxcareer.com/compar...gement-systems

It talks about the apt, yum, pacman, and portage package managers.

Not going to happen. Produce a list of the packages installed via yum on your centos machine, find the apt equivalents, and then use apt-get to install them on Ubuntu from the Ubuntu repository.

Thanks to all for your interest in my post.
I am follow all procedure in making yum server in cent_os and also stored there .deb packages.
Through ftp it will be connected but i want to that my ubuntu system get all packages through yum as like rhel or cent_os worked..

PLease all suggested me asap..

wesaus32,
Thank you for that information. Tell me that how get the packages through apt-get command.

nitin.pant, which operating system is installed?

As you've been told repeatedly - Ubuntu does not use yum. It doesn't matter how many times you ask, it's not going to happen. Also, you WILL brick your system if you attempt to convert your centos rpm packages to deb and install them on Ubuntu, do not do it.

As I said before:

The yum equivalent on Ubuntu is apt-get. So you might have used something like
on Ubuntu you will use
Ubuntu and CentOS are not binary compatible, so not only are the package managers different, but the whole package architecture is different. Each application will likely have different perquisites and even a different folder structure. So even if you did manage to get yum running on Ubuntu, like suicidaleggroll said, bank on fracking up your system.

If you have no clue what I'm talking about, read this.

Hope that clears this up.

In my server side i used centos and we have client ubuntu.

As you said, i understand what you said but my question is. I want my ubuntu dont get any packages through online they should get there all packages form server.i.e centos

Then set up a local apt-get repository. There are numerous guides online showing how to do it.
