I am on Ubuntu, and my copy of julia was installed with apt-get install julia.

I was trying the curve fitting tutorial found here (http://www.walkingrandomly.com/?p=5181) but I kept getting the error "curve_fit not defined". Yes, I have done "Pkg.add("Optim")" and "Pkg.add("LsqFit")", that doesn't help. Apparently, nobody else on the internet has ever had this problem. I'm surprised.

Also, it doesn't seem like I can find the version number of Julia that I'm using. Following this (http://stackoverflow.com/questions/25326890/how-to-find-version-number-of-julia-is-there-a-ver-command) just gives me the error "verbose not defined". Is every piece of documentation about Julia from earlier than 6/2015 invalid now? The responses I found here are pretty useless, as curve_fit doesn't even work by itself.

Call the function versioninfo(), or enter the constant VERSION

Depending on what version of Ubuntu you're using, the Julia that you installed from apt-get is probably quite out of date. It's better to use the more recent tarball releases available from www.julialang.org/downloads.

Try the advice that Tony gave you, use the tarballs.

JLTAR=https://julialang.s3.amazonaws.com/bin/linux/x86/0.3/julia-0.3.11-linux-i686.tar.gz
mkdir julia && wget -O - "${JLTAR}" | tar -C julia \
--strip-components=1 -x -z -f - && julia/bin/julia

As for guides on Stack Overflow and personal home pages, it is
difficult for it to be in sync with a fast moving target that still
has not had a 1.0 release. For up-to-date documentation, please see
the official homepage [1].
