Where is this deb.opera.com repository still coming from?

[Tech Geek <techgeek12345@gmail.com>]

I was under the impression that whenever you run apt-get update it reads the repositories listed in /etc/apt/sources.list file and fetches the contents of it but apparently something else is going on too...

 

So somtime back I added the following line in my /etc/apt/sources.list:

# Opera Browser Repository
deb http://deb.opera.com/opera/ stable non-free

 

and then installed opera browser from it:

apt-get update; apt-get install opera

 

Now after sometime I removed the opera repository line from sources.list (but the package is still installed) and then when I ran apt-get update, I still saw apt-get trying to read the opera repository like this:

debian:/var/lib/apt# apt-get update

Reading package lists... Done
debian:/var/lib/apt#

 

Here is my sources.list file that I used to ran the above apt-get update command:

#Stable
deb     http://mirrors.kernel.org/debian stable main
#deb-src http://mirrors.kernel.org/debian stable main

#Testing
#deb     http://mirrors.kernel.org/debian testing main
#deb-src http://mirrors.kernel.org/debian testing main

#Unstable
#deb     http://mirrors.kernel.org/debian unstable main
#deb-src http://mirrors.kernel.org/debian unstable main

#For Security patches
deb http://security.debian.org/ stable/updates main

#Debian Backports
#deb http://www.backports.org/debian/ lenny-backports main

 

And here is the output of the package lists of the repositories:

debian:~# ls /var/lib/apt/lists/
deb.opera.com_opera_dists_stable_non-free_binary-i386_Packages
deb.opera.com_opera_dists_stable_Release
deb.opera.com_opera_dists_stable_Release.gpg

Not sure what is happening and from where apt-get is still seeing the opera repo line.

 

I have always use apt-get.

 

Thanks
