it depends what you want to fix. If you can add a bit more detail to the question, it has more chace of being answered correctly :) –  SimplySimon Jun 23 '13 at 9:42
What are you trying to fix? –  Mitch Jun 23 '13 at 9:43
Are you looking for a way to display an error message saying "fix missing" at the terminal with for example echo? Or are you running into an error message? In the latter case, please edit your question to include at least: what you're trying to accomplish, what exact command you're running, what happens instead (including exact error message). –  gertvdijk Jun 23 '13 at 9:49
sudo apt-get update --fix-missing ? –  Mateo Jun 23 '13 at 10:33

To fix missing PPA's, then you would just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:

sudo apt-get update --fix-missing

How do you know this question is about APT? Currently the question doesn't say that. Also, if it is, then what makes you think this solves issues with PPAs? This command won't delete PPAs installed. –  gertvdijk Jun 23 '13 at 13:27
@gertvdijk I don't. I did some research, and I made an educated guess. If it is fine if not oh well. Plus I didn't say that this delete PPA's. Plus as Jai said it in the Ubuntu Manuals :) –  Mitch Jun 23 '13 at 14:51

I will try to answer your question with available information.

what does the man page saying ??

-m, --ignore-missing, --fix-missing
           Ignore missing packages; if
           packages cannot be retrieved or
           fail the integrity check after
           retrieval (corrupted package
           files), hold back those
           packages and handle the result.
           Use of this option together
           with -f may produce an error in
           some situations. If a package
           is selected for installation
           (particularly if it is
           mentioned on the command line)
           and it could not be downloaded
           then it will be silently held
           back. Configuration Item:

How do you know this question is about APT? I think you also should include what manpage you are referring to and how a user would have guessed to look in that one. –  gertvdijk Jun 23 '13 at 13:27
No, there's no single Ubuntu manpage. It's the apt-get manpage of the version in Ubuntu 10.04. –  gertvdijk Jun 23 '13 at 13:32
@gertvdijk , sorry my friend , now you can check here manpages.ubuntu.com/manpages/raring/man8/apt-get.8.html –  raaz Jun 23 '13 at 13:34
