sorry for asking a question which arised many times here. I read all respective threads and nothing helped.

My OS is Fedora 25, TexLive 2016. The code (ruhyphen.tex) is:



The output of the latex command is:

This is pdfTeX, Version 3.14159265-2.6-1.40.17 (TeX Live 2016) (preloaded format=latex)
 restricted \write18 enabled.

The packages installed:


After installation of these, I run fmtutil-sys --all. The output suggests that the hyphen files were processed:

Preloading the plain format: codes, registers, parameters, fonts, more fonts,
macros, math definitions, output routines, hyphenation
UTF-8 Russian hyphenation patterns

In the thread No hyphenation patterns were preloaded Lerenn wrote that the problem with Fedora was possibly that the /usr/share/texlive/texmf-dist/tex/generic/hyph-utf8/loadhyph directory is not standard and that including


solved his problem. In my case this does not change anything.

Any help would be welcome. Thanks, Igor

    it works for me but your format seems very wrong Babel <3.9r> and hyphenation patterns for 3 language(s) loaded. with an up to date tl2016 I get Babel <3.9r> and hyphenation patterns for 83 language(s) loaded The log you show of a format is of plain tex fomat, can you show the log from making latex.fmt – David Carlisle Dec 25 '16 at 18:49
  • @David Carliste Thanks for the answer. Yes, the hyphenetion patterns for only 3 languages confused me, too. As for the log you are asking about, sorry I don't quite understand - do you mean the full output of fmtutil-sys --all ? – Igor Dec 25 '16 at 19:01
  • The usual suggestion is to install vanilla TeXlive. If you insist on using the packages from somewhere else, please file bug reports there. – Martin Schröder Dec 25 '16 at 19:42

    I'm voting to close this question as off-topic because theissue was due the a stray file in the system. – egreg Dec 26 '16 at 10:02

    @egreg It was not clear to me when I posted the question what was the reason for the problem. It might be package or texlive - related. the question may be off-topic in regard to texlive. But it is was a real problem so I think keeping this thread here can help others who encounter the same problem. – Igor Dec 26 '16 at 10:17

Thanks to David's comments, the issue is resolved. In F25, there are 2 language.dat files:




The former does not contain russian lines. The latter does:

russian loadhyph-ru.tex

Following the pattern for english in the /etc/.../language.dat file I added the lines to it

russian ruhyphen.tex

After that, I run "fmtutil-sys --all". And this worked! babel tells me that hyphenation patterns were loaded for 12 languages and did not complain about Russian. So it must be a bug in F25 texlive packaging. Installing Russian components should update the /etc/.../language.dat file but it does not. The header of the file says "Do not edit manually, the file is generated by tlmgr". But tlmgr is excluded from F25 texlive package and not available in any repos. The reason is Fedora does not want any package to be maintained outside the official package manager dnf (which is reasonable). If only they did their packaging properly... Anyway, the issue can be closed. Thanks a lot to all of you.
