I am new to ubuntu OS. I am trying to install skype on ubuntu 12.04. I am following a tutorial that says

sudo apt-add-repository “deb http://archive.canonical.com/ $(lsb_release -sc) partner”

but when i execute this command, it says:

lsb_release-sc: command not found

Some reason you're missing that executable. I have it on mine and according to dpkg -S, it is part of the lsb-release package.

ned@flanders:~$ dpkg -S `which lsb_release`
lsb-release: /usr/bin/lsb_release

What does your system say about that package?

ned@flanders:~$ apt-cache policy lsb-release    
  Installed: 4.0-0ubuntu20.3
  Candidate: 4.0-0ubuntu20.3
  Version table:
 *** 4.0-0ubuntu20.3 0
        500 http://ftp.utexas.edu/ubuntu/ precise-updates/main amd64 Packages
        100 /var/lib/dpkg/status
     4.0-0ubuntu20 0
        500 http://ftp.utexas.edu/ubuntu/ precise/main amd64 Packages

You can install with sudo apt-get install lsb-release provided your apt sources are correct.


sudo apt-add-repository “deb http://archive.canonical.com/ $(lsb_release -sc) partner”

lsb_release-sc: command not found

I suspect that you simply forgot to put a whitespace between the command (lsb_release) and its options/switches (-sc).

  • His command does not work (with spaces) on my PC, so I suspect other issues ..

Possible solution:

You are using the non-std apt-add- (should not matter), but are also using Windows-type unique characters for 'open-quote' and 'close quote'.

Try this instead:

sudo add-apt-repository "deb http://archive.canonical.com/ $(lsb_release -sc) partner"

You don't need to do this step manually. Use the Ubuntu Software Center and look for Skype.

You will have a button to use the partner source (Use Source). And then you can click to install Skype.

No command line is required.

  • Yes installed it from software update center. Thanks :)

    This might be a solution for skype, but it is not a solution for the question "lsb release not found" please remove this as the accepted answer Aug 23, 2016 at 15:20
  • @JamesDunmore Sorry but the question was about Skype installation which resulted in the error lsb_release not found. So this is the response to the problem. Perhaps the question could be improved so it is clearer.

  • @Huygens sorry yes, I didn't mean to say that your answer wasn't helpful. Perhaps updating the thread title to be skype related - lots of people, including myself landed here because the thread title is "lsb_release command not found" and this chosen answer doesn't actually fix that. I know, I'm being pedantic - your answer is perfect for solving his problem :) Aug 25, 2016 at 10:52
