I can not install most of the software as not all of the software has a button to install. is this an error? or dependency problem if so how do i fix it?
i have found the answer, firstly navigate to system-> administration-> software sources
then go to update and at the bottom of the window their is an option to select what type of update you want. select -normal update- the close the window and reload.
the problem should be fixed. -thank you for those who tried to answer it really helped.
Try reinstall Software Centre by the following command in Terminal:
sudo apt-get clean; sudo apt-get update; sudo apt-get -y --reinstall install software-center
If this doesn't help, run
software-center from the Terminal, you should see the errors, this should point you to the more specific issues.
I didn't see the button too, I found that my proxy settings were not properly set. So if you are under a proxy,
Get this file : https://www.dropbox.com/s/uxbi3rl2p9wmsx7/setproxy.py
Then in terminal,type in-
python setproxy.py <proxy ip><space><port><space><username><space><password>;
Now check the software center for install button.
