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.

Answer 2

try to :

sudo apt-get update

then, open Ubuntu Software Center again.

Answer 3

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.

Answer 4

Do you have examples of such software? It might be software that has no 64-bit version, or it might not be available from the currently configured repositories (software sources) for another reason...

Answer 5

On Ubuntu 18.04

sudo apt update
sudo apt install gnome-software

Answer 6

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.
