Got a e-mail have to renew but can't

Got a e-mail today that "Let's Encrypt certificate expiration notice" in 17 days so have some time. But wanted to see if can renew it now. I wanted to update it so here is the commands that did not work I don't know why.

root@:~/letsencrypt# ./letsencrypt renew
-bash: ./letsencrypt: No such file or directory
root@:~/letsencrypt# cd ..
root@:~# git pull GitHub - certbot/certbot: Certbot is EFF's tool to obtain certs from Let's Encrypt and (optionally) auto-enable HTTPS on your server. It can also act as a client for any other CA that uses the ACME protocol.
fatal: Not a git repository (or any parent up to mount point /media/6TB)
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).
root@:~#

I do have a link to another part for my root directory, to /media/6TB/USBdisk2-3TB/root/letsencrypt I don't think that is the problem.

Did just a git pull but it seems like it all most updated but not. Looked like this:

Please, commit your changes or stash them before you can merge.
Aborting
root@:~/letsencrypt# ./letsencrypt renew
-bash: ./letsencrypt: No such file or directory
root@:~/letsencrypt#

Any one know what's wrong?

I think I may of fix it. Just did a:

Did a git stash then git pull that look like it updated it. Then did:

./letsencrypt-auto

It came back at the end with:

Your cert will
** expire on 2016-05-19. To obtain a new version of the certificate in**
** the future, simply run Let’s Encrypt again.**

So looks like I am all set till May 19TH.
