My Internet connection is working, but I cannot download anything from software center and I cannot update or upgrade from the terminal.
I changed my /etc/apt/sources.list
to activate all the sources I have. None of them worked.

Do a backup of your sources.list
file.
cd /etc/apt/
sudo cp sources.list sources.list.001 # if sources.list.001 doesn't exist
After generate a default set of sources e.g. from Ubuntu Sources List Generator. Here you can select your release and country. Else you can find on internet e.g. here too.
Then copy it inside your sources.list
file
sudo nano /etc/apt/sources.list
# Now paste the list, save and exit
sudo apt-get update # to resynchronize the package index
# files from their sources
sudo apt-get -f install # just in case you need to fix something
Now it would be possible to use the software centre too.
