[Bug 854841] Re: add-apt-repository will write duplicate entries to /etc/apt/sources.list

[John Doe]

This bug is NOT fixed yet!

I am getting:

W: Duplicate sources.list entry http://ppa.launchpad.net/xxxxx oneiric/main amd64 Packages (/var/lib/apt/lists/ppa.launchpad.net_xxxxx_dists_oneiric_main_binary-amd64_Packages)
W: Duplicate sources.list entry http://ppa.launchpad.net/xxxxx/ubuntu/ oneiric/main i386 Packages (/var/lib/apt/lists/ppa.launchpad.net_xxxxx_dists_oneiric_main_binary-i386_Packages)
W: You may want to run apt-get update to correct these problems

After running sudo apt-get update, this problem is not resolved.

(seems like some are not listed here)

Corrective measure needed:
Implement a check to see if any PPA was already added prior to adding it to the system.

Title:
  add-apt-repository will write duplicate entries to
  /etc/apt/sources.list

Status in “software-properties” package in Ubuntu:
  Fix Released

Bug description:
  Hello,
  Add-apt-repository command allows one to add duplicate entries to sources list. Would it be possible to improve this utility it so it adds only unique entries?

  Eg. This command, when run twice, adds duplicate entries.
  $ sudo add-apt-repository "deb http://archive.canonical.com/ubuntu oneiric partner

  $ grep -Ri partner /etc/apt/sources.list
