[BUG] LaTeX Error: File `luatex85.sty' not found. (PGFPlotsX backend)

[martincornejo]

In a linux machine I seem to have problems with the PGFPlotsX backend. For instance, the following trivial example throws an exception:

julia> plot(rand(5))
! LaTeX Error: File `luatex85.sty' not found.

Type X to quit or <RETURN> to proceed,
or enter new name. (Default extension: sty)

Enter file name: 
! Emergency stop.
<read *> 
   
l.530 \RequirePackage
                   {pdftexcmds}
End of file on the terminal!

Hi!

The issue comes from a TeX Live update that excludes the luatex85.sty from the "default" installation. Install luatex explicitly to fix the issue:

sudo apt-get install texlive-luatex

For any other backend-related problems, I suggest to file an issue at PGFPlots.jl directly: https://github.com/JuliaTeX/PGFPlots.jl/issues
