App Center not working in elementary OS?

Question

linux

Installed elementary OS today. Launched, everything worked fine, but after a while the Application Center stopped starting. Just a jumping icon.
Tried uninstalling and reinstalling - didn't help. I tried to run through the terminal, this is what it gives

2016-01-31 18:32:10,569 - softwarecenter.ui.gtk3.app - INFO - setting up proxy 'None'
Traceback (most recent call last):
File "/usr/bin/software-center", line 130, in
app = SoftwareCenterAppGtk3(options, args)
File "/usr/share/software-center/softwarecenter/ui/gtk3/app.py", line 407, in __init__
self.icons)
File "/usr/share/software-center /softwarecenter/ui/gtk3/panes/historypane.py", line 79, in __init__
self._get_emblems(self.icons)
File "/usr/share/software-center/softwarecenter/ui/gtk3/panes/historypane.py" , line 199, in _get_emblems
pb = icons.load_icon(emblem, self.ICON_SIZE, 0)
gi._glib.GError: An error occurred while opening file:No such file or directory

How to fix it?

Answer 1

sudo apt-get update helped me =)

Answer 2

In tweaks, change the theme of the icons, I had the same problem
