# How to install packages which I am not able to find in TeX Live Utility? [duplicate]

Using this tex on TeXworks, I get an error. The code is an output from pandoc converting from markdown to tex.

I checked if I have all the packages with TeX Live Utility. I found the followings.

1. When I check fontenc I found that I have greek-fontenc package.
2. I am not able find lmodern and fixltx2e
3. For inputenc, I have greek-inputenc
4. I am not able find longtable in TeX Live Utility
5. I have all other packages.

Now my question is how to install packages which I could not find it in TeX Live Utility?

I know this is a newbie question, but I appreciate your help.

Please post a Minimal Working Example of code which people can compile (or fail to compile) to reproduce the problem. What you've posted doesn't make it clear what the source of the problem is. I suspect that you have loaded fontenc with option T1 but that the cm-super fonts are either not available or not found for some reason. You could load a different font if you have one installed. For example, \usepackage{lmodern} might work. But it is kind of hard without seeing the code or knowing really anything about what you have installed or not. –  cfr Mar 10 '14 at 23:23
What TeX distribution are you using? –  egreg Mar 10 '14 at 23:33
typing ecrm1000 into the above search box shows lots of solutions to this problem tex.stackexchange.com/search?q=ecrm1000 –  David Carlisle Mar 10 '14 at 23:49
note that the packages that you mention fontenc fixltx2e inputenc and longtable are all part of the core latex distribution not contributed additions. If you have latex, you have them already. –  David Carlisle Mar 11 '14 at 0:13

I need to run sudo tlmgr install ec in the terminal. It works fine now. Thanks for your comments.
