The yum package manager comes from RedHat and its derivatives. It installs rpm packages from repositories that store such packages. The Debian (and by extension, Ubuntu) repositories have .deb packages instead. The equivalent of yum in the Debian/Ubuntu world is apt-get. I have no idea why you ended up with yum installed on your Ubuntu system but it's not the tool you want to use.

What you're after is:

sudo apt-get install tftp tftpd syslinux apache2 dhcpcd

In any case, that's my best guess since you don't actually explain what you're trying to install. There's no tftp-server package in Ubuntu so I'm guessing you want tftpd which is a server that supports the TFTP protocol. Likewise, there's no httpd in Ubuntu but I'm guessing you want to install the apache2 webserver and a dhcp client (dhcpd).

There are no enabled repos.
 Run "Yum repolist all" to see the repos you have.
 You can enable repos with yum-config-manager --enable <repo>

#yum repolist all
repolist: 0

  Could you please clarify what Operating System you are running? yum is a RedHat & co. command, and while it is possible to install on Ubuntu, there's not much reason to. Please edit your question and clarify whether you're using Ubuntu or not.

  Tftp is the user interface to the Internet TFTP (Trivial File Transfer Protocol), which allows users to transfer files to and from a remote machine. The remote host may be specified on the command line, in which case tftp uses host as the default host for future transfers.

  is this what you are looking for? then it's tftp. You can list all available tftp packages with command: apt-cache policy tftp*

  You want to install CentOS? 1) the commands you are using are completely irrelevant then and 2) your question is completely off topic.
