Problem with yum etc after installing Ubuntu 7.10.....

[Peter Teoh]

a.  install ubuntu
b.  apt-get install yum*
c.  apt-get install git

Next I tried "git", I got "command not found", but reattempted to
"apt-get install git" will give me:

root at oracledaddy:/tmp# apt-get install git
Reading package lists... Done
Building dependency tree
Reading state information... Done
git is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 211 not upgraded.

I tried to yum install some other stuff, I got the following:

There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

  No module named cElementTree

Please install a package which provides this module, or
verify that the module is installed correctly.

It's possible that the above module doesn't match the
current version of Python, which is:
2.5.1 (r251:54863, Oct  5 2007, 13:36:32)
[GCC 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)]

If you cannot solve this problem yourself, please send this
message to <yum at lists.linux.duke.edu>.

Can someone help?
