Since it was there earlier, it is tracked twice now:
- User input is combined with format string in org-latex-src-block
- Bug: Percentage in caption does not work in LaTeX export

Let's assume that one entry is to fix "minted" and another one for 
"listings" environment. Though one more obscure issue remains: 
"multicolumn" option does do what can be expected from its name.

org-latex-src-block: Not enough arguments for format string


Confirmed

User input is combined with format string in `org-latex-src-block' so 
percent character in caption is treated as a format specifier. Maybe 
emacs versions newer than 26 does not throw an error on extra specifier 
with missed argument. =:latex-cation-above nil= might still cause 
corrupted LaTeX code.


Code of `org-latex-src-block' is quite convoluted to provide a quick 
fix. Besides particular reported case it is better to check variants 
with listings and minted packages, custom environment.


Absence of language and line numbering option are irrelevant. Backslash 
before percent likely should not be used in Org files. My minimal example


#+caption: User input "%S" is combined with format string
#+begin_src emacs-lisp
  t
#+end_src

P.S. "Not enough arguments for format string" error usually means that a 
string provided by user is passed as format or incorrect number of 
arguments is specified for a format-like function. The former case is a 
quite frequent mistake:

-

Use

not just

Hello Timothy,

   Yeah, I tried, and it did not worked.

   I had exchanged emails with Eric, we came to the conclusion that the source 
of the problem might be a clash between my emacs version 26 and an updated 
version of the org-mode. I have to try to update my emacs to see where it goes 
from there, but have to find some time to do it.

   I was thinking also I might had screw up my installation some time ago by 
attempting to install Org-roam. It stopped at some point complaining about not 
finding the database, which, from what I understand, was supposed to be 
downloaded and compiled manually.

   Anyway, I'll try updating my emacs with a fresh install, I'll keep you 
inform. 

Thank you for the follow-up !

Have you been able to give this a shot?

whereas for me it fails because no language was given for the src block,
i.e. different error message in the latex compilation.  What happens if
you do specify a language?

If I specify a language, the export is fine with % unescaped, by the
way.

Bug: Percentage in caption (even escaped) does not work in LaTeX export

[Charest, Luc]

Hello,

   I simplified the problem down to :

#+CAPTION: Org Mode works 99.99\% of the time.
#+BEGIN_SRC -n
// this is only a proof of concept
#+END_SRC

As soon as I put the percentage sign in the caption, the LaTeX export backend 
fails with this message :

org-latex-src-block: Not enough arguments for format string

I tried "%", "\%", "\\%", "%%"... nothing works !

If I get it wrong, sorry but please update the documentation accordingly, as I 
found nothing in the specs regarding this matter specifically.

My versions :
Emacs  : GNU Emacs 26.2 (build 1, x86_64-w64-mingw32)
of 2019-04-13
Package: Org mode version 9.4.6 (9.4.6-4-g093c94-elpa)

Thanks !
