I tried to reinstall pip but there seems to be a problem with the location of some files related to the update manager.
sudo apt-get install python-pip
[sudo] password for benoit:

E: The package update-manager needs to be reinstalled, but I can't find an archive for it.
And then I get the following from an attempt to update the package update manager.
$ sudo apt-get update

I then tried to regenerate the source.list file, which didn't seem to solve the problem. Here's my source.list file as it is now.
I don't quite see where I should investigate next. Could someone help?
