Errors when trying to install atom

[Jim Byrnes]

I am evaluating kubuntu14.04 in virtual box on my Ubuntu 12.04 system. I 
came across an editor called atom and decided this would be a good place 
to test it.  Following the instructions on the atom website produced the 
following errors:


jfb at Kubuntu14-04:~/Downloads$ sudo dpkg -i atom-amd64.deb
Selecting previously unselected package atom.
(Reading database ... 201246 files and directories currently installed.)

dpkg: error processing package atom (--install):

I searched Muon but found none of the packages I needed.  I haven't been 
trying out kubuntu for that long so I don't know the best way to proceed.

Thanks,  Jim
