I'm having a problem with Software Center since I tried to add Spotify repositories to sources.list. It doesn't open at all.

I tried reinstalling Software Center, but it sends this error:

E:Type «» is not known on line 59 in source list /etc/apt/sources.list

I'm not sure if this is the real problem, but apart from this everything seems to be ok.

Edit /etc/apt/sources.list to fix the broken lines.

To do this, run this command in a Terminal with Ctrl+Alt+T:

sudo -H gedit /etc/apt/sources.list

Find and comment or delete line 59. It should look like:

deb ...

Save the file and quit the text editor. Then run this command in a terminal:

sudo apt-get update
