I try to install a new ppa entry and when I update from command line I received a duplicate (error) message. I know what meens that and how to solve manually with Ubuntu Tweak or command line. Is any automated way to solve this problem when I install duplicate entries? like a command which find the duplicates and erase them or a software.

I googled for such a tool, but I didn't find any.. So, I ended up coding one myself with PHP.

Sorry for the dirty unorganized source code..

chkdup - Screenshot:

Requirements:

  1. PHP.
  2. Sudo.

Installation:

  1. Open the terminal.
  2. To install PHP if you don't have it, type: sudo apt-get install php5 php5-cli.
  3. Download the chkdup.
  4. Extract the file anywhere you like.
  5. Type: sudo sh install.sh.

Uninstall:

  1. Open the terminal.
  2. Go to the path you extracted the tool in.
  3. Type: sudo sh uninstall.sh.

How to use it:

Just open the terminal and type sudo chkdup.

FAQs:

What does the install.sh do ?

  • The installer will move the chkdup.php to /opt/ then will create a symbolic link in /usr/bin/.

What about the uninstall.sh ?

  • The uninstaller will remove the following files:

    1. install.sh
    2. /opt/chkdup.php
    3. /usr/bin/chkdup
    4. itself "uninstall.sh"

Is it safe to use chkdup ?

  • Yes it is, since it takes a backup of the current sources.list before attempting to do anything. But I'm not responsible if anything happened. The full responsibility will be yours.

Y PPA Manager can remove duplicate PPAs with a click

I try to use Y PPA Manager but it didn't remove the duplicates. Were to send you a print screen? – Vassilis Mar 25 '11 at 9:56
@Vassilis: please report the bug @ Launchpad: bugs.launchpad.net/y-ppa-manager if it's about a PPA. But please note that Y PPA Manager only works with PPAs so if it's some other repository in your main sources.list file, it won't work... (it's not intended to work with that). – Alin Andrei Apr 15 '11 at 10:51
