I uninstalled it from the software center....once it happened, I wanted to install it again, but it shows that it is there (weird). I did an update and it is gone from the PPA.

How can I install it again or check if it is there or damaged? Is it really important to have the synaptic manager if I mainly use the software manager?

Use apt-get as suggested below, but do not panic, you can do everything that synaptic does with apt-get itself. There are also other alternatives for installing such as aptitude. – v010dya Dec 4 '13 at 10:17

Try these commands in terminal,

sudo apt-get purge synaptic    
sudo apt-get install synaptic


sudo apt-get install --reinstall synaptic

Yes,it was really important.You can easily check which packages are installed and which are not installed through synaptic.

Thanks for the reply. I have just done the 1st option, but when I update from the terminal, I get these messages: "W: Failed to fetch… 404 Not Found W: Failed to fetch… 404 Not Found W: Failed to fetch… 404 Not Found How can I update and put the synaptic PPA again? – Elysium Dec 4 '13 at 11:34

Thanks again. This is the part with the error message: – Elysium Dec 4 '13 at 12:04
you don't need to update from the terminal,just run the above commands. – Avinash Raj Dec 4 '13 at 12:12
I have already run that command and synaptic is already installed. but I am wondering why the ppa is giving me this error message when I update my system from the terminal? – Elysium Dec 4 '13 at 12:14
