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.

source.list

I don't quite see where I should investigate next. Could someone help?

  • The things you are showing us all appear to be warnings - what are the actual errors? – steeldriver Jun 21 '17 at 12:10
  • I thought this could be an indication of something problematic. I edited my post to provide more background to my issue. In short, I need to reinstall my update manager but I don't quite see where to investigate. – BenoitA Jun 21 '17 at 16:15

    Well I suggest you clear the errors (by removing repositories from your main /etc/apt/sources.list file that are also specified in files inside the /etc/apt/sources.list.d/ directory - the W: messages tell you which those are) and see if it makes any difference. – steeldriver Jun 21 '17 at 16:35

  • @steeldriver - I have. I regenerate the source.list main file and have edit the repository you mentioned.

  • @luv.preet - Thanks for pointing out. I had already read this tread. I tried uninstalling with sudo apt-get --purge remove update-manager and other variants, but I get the exact same output, that archive files are missing. – BenoitA Jun 21 '17 at 20:04

Try installing the update-manager package manually.

  1. Download the package using on of the links from here. You can choose any one, but it would be preferable to use the one for your country.

  2. Install by running dpkg -i /file/you/downloaded

If there are any errors, could you please post them in a comment.

  • Thanks for the quick reply. There still seems to be some corrupted files elsewhere. I also very recently updated python and am wondering if this is where I might have messed up. Here is what I get out of the install you suggested. I seem to have to paste this over a few comments, as their are limited in size. – BenoitA Jun 21 '17 at 19:38
