I uninstalled Bumblebee, but now my video card is not working properly. I tried to update its video driver, but now I just got the message

An unresolvable problem occurred while initializing the package information.

Please report this bug against the 'update-manager' package and include the following error message:

'E:Type 'ain' is not known on line 3 in source list /etc/apt/sources.list.d/bumblebee-stable-precise.list'

either when I try to update by terminal and also when I open the package manager.

I would be glad in having some help!

What do you mean by "my video card is not working properly"? –  Flimm Feb 5 '13 at 9:31

This is not a bug, please do not report it. That message is just caused by a malformed entry that starts with ain instead of deb or deb-src. –  Andrea Corbellini Feb 5 '13 at 12:34

This isn't a major error, just a wrong line added in /etc/apt/sources.list.d/bumblebee-stable-precise.list, and is in no way related to "video card is not working properly".

You can remove the Bumblebee PPA file to fix this using the commands below:

sudo rm /etc/apt/sources.list.d/bumblebee-stable-precise.list
sudo apt-get update

Now you shouldn't see this error any more.

And if you want to continue having the Bumblebee PPA, re-add it using:

sudo add-apt-repository ppa:bumblebee/stable
