Natty 11.04 beta 2: Is this a bug in the Ubuntu Updates in Software Center?

Asked by Michael Nguyen

I am running Ubuntu "Natty Narwahl" 11.04 in Ubuntu Classic Session.

In the Ubuntu Software Center's Software Sources, under the "Updates" tab, there are duplicate items in the Ubuntu updates. For example, the second item is "Important security updates (natty-security)" but so is the third one. The full list looks like this:

 Ubuntu Updates

 [ ] None (natty)
 [ ] Important security updates (natty-security)
 [ ] Important security updates (natty-security)
 [ ] Recommended updates (natty-updates)
 [ ] Recommended updates (natty-updates)
 [ ] Pre-released updates (natty-proposed)
 [ ] Pre-released updates (natty-proposed)
 [ ] Unsupported updates (natty-backports)
 [ ] Unsupported updates (natty-backports)

The first "important security updates", "recommended updates" and "pre-released updates" are checked. Screenshot available upon request.

Also, I have the Pidgin PPA installed among some other non-canonical PPA but I'm not sure if they affect the Ubuntu updates.

One will be source, the other will be binaries. This is normal.

How will I know which is which? Should I assume the top on is binaries and the bottom source code?

One will have:

(source)

on the end.

It doesn't. Check the post. Perhaps you need a visual. Here: http://img219.imageshack.us/i/screenshothfl.png/

     This is a bug that is probably related to three others, which I've linked to on this page.. They are apparently related to the bugs present in python-apt-common as of the latest version in natty (0.7.100.3ubuntu5). This doesn't appear to have anything to do with the sources, I've searched for duplicates using chkdup (checks for duplicate sources) and also manually examined the sources.list file in /etc/apt, and the sources.list.d folder in my install, but nothing appears out-of-line, so this must have to due with a bug in the python script. May be worth looking in this folder location:
     "/usr/share/doc/python-apt-common"
and the file "python-apt-common" in "/usr/share/lintian/overrides".
