"apt-get install" doesn't work on 12.04

[smss]

When I want to install kdevelop through Ubuntu Sofware Center, I faced with this error : "Package dependencies cannot be resolved".
I updated the resources and try it again, But the error wasn't changed.

Can anybody help me with this problem?
Thanks.

Have you tried...


sudo apt-add-repository ppa:kubuntu-ppa/backports


sudo apt-get install kdevelop

[steeldriver]

it looks like you pasted a lot of extraneous text into the command line e.g.



smss@smss-network:~$ smss@smss-network:~$ sudo apt-get install kdevelop-dev


and



smss@smss-network:~$ Reading package lists... Done
Reading: command not found


etc.

[smss]

Excuse me stelldriver, I Updated it now.

Petro Dawg, For what I couldn't install programs through normally way?

Petro Dawg, For what I couldn't install programs through normally way?

I do not understand your question.

Were you able to install the program through terminal using the method I suggested? If not, please copy and paste any new errors in the terminal output for further troubleshooting.

In fact, I want to tell "apt-get" is not healthy in my PC...
When I want to install any program such as "kdevelop" through terminal or other ways ( e.g. Ubuntu Software Center ), I could not install its and I faced with "E: Unable to correct problems, you have held broken packages."
