software centre error on ubuntu

Question

So i am new to Ubuntu and I am currently using Ubuntu 17.04. I tried updating software through the "software updater". After this I had trouble with the software center when I clicked on its icon it just showed the loading graphics where the mouse is placed .the Application doesn't open. so I tried reinstalling software center.this is the error I got after trying to install software center

[edit 1] i understood that there is no package called software-centre. i installed gnome-software but my main issue still persists.

Answer 1

I personally wouldn't worry about the software centre. I never use either of them (Ubuntu Software/Ubuntu Software Centre). I always look up what kind of program I'm wanting to install, search how to install it, then follow the instructions. With some software, you have to add a PPA, install, say, snap or something, and all of this would be listed in the installation instructions. I just find that there is typically better software available from sources other than the software centre. However, if you're just trying to update your software, you can run:

sudo apt-get update
sudo apt-get upgrade

Answer 2

The error message that you got:

E: package 'software-center' has no installation candidate  

means exactly what it says. There is no Ubuntu Software Center package in the default 17.04 repositories. Instead 17.04 uses Ubuntu Software (gnome-software) as the default GUI software management application.

Close the Ubuntu Software window if it is open. Open the terminal and type:

rm -r ~/.local/share/gnome-software
