I think this is fixed with the -7 update that is building now, there were some incorrect Obsoletes affecting texlive-kpathsea. Do you have the matching texlive-kpathsea installed?

I have the latest for both, though the svn numbers don't match.

rpm -qa | grep kpathsea
texlive-kpathsea-bin-svn40473-6.20160520.fc26.1.x86_64
texlive-kpathsea-svn41139-6.fc26.1.noarch

I'll try out -7 when it's finished

Okay, and just to sanity check, /usr/share/texlive/texmf-dist/web2c/fmtutil.cnf exists?

Yes, it exists

grep -v "^#" /usr/share/texlive/texmf-dist/web2c/fmtutil.cnf

latex pdftex language.dat -translate-file=cp227.tcx *latex.ini
pdflatex pdftex language.dat -translate-file=cp227.tcx *pdflatex.ini

Same behaviour with -7

$ rpm -qa | grep kpathsea
texlive-kpathsea-svn41139-7.fc26.1.noarch
texlive-kpathsea-bin-svn40473-7.20160520.fc26.1.x86_64

$ kpsewhich -all fmtutil.cnf
(no output)

$ mktexfmt latex.fmt
(Finds no fmtutil.cnf files)

I ran strace for kpsewhich and compared F24 with Rawhide. It seems the problem is the ls-R files, particularly /usr/share/texlive/texmf-dist/ls-R are missing. It looks like these are ghost files and are supposed to be generated with texhash, but it looks like that isn't happening.

Okay. I figured this out. I moved to using triggers in the texlive package to try to speed up things.

Before, we had this (on every subpackage):

%postun
if [ $1 == 1 ]; then
  mkdir -p /var/run/texlive
  touch /var/run/texlive/run-texhash
else
  %{_bindir}/texhash 2> /dev/null
fi

%posttrans
if [ -e /var/run/texlive/run-texhash ] && [ -e %{_bindir}/texhash ]; then %{_bindir}/texhash 2> /dev/null; rm -f /var/run/texlive/run-texhash; fi

Now, we have this (only on the texlive core package):

%transfiletriggerin -- %{_texdir}
%{_bindir}/texhash 2> /dev/null
export TEXMF=/usr/share/texlive/texmf-dist
export TEXMFCNF=/usr/share/texlive/texmf-dist/web2c
export TEXMFCACHE=/var/lib/texmf
%{_bindir}/mtxrun --generate &> /dev/null
%{_bindir}/fmtutil-sys --all &> /dev/null

%transfiletriggerpostun -- %{_texdir}
%{_bindir}/texhash 2> /dev/null

That _should_ result in texhash being executed once after transaction for all installed packages that contained file(s) that matches prefix of this trigger (/usr/share/texlive). Also executed after transaction if there was a package containing this file trigger in that transaction and there is/are some files(s) matching prefix of this trigger in rpmdb. 

But! Here is the issue (I think). I put the triggers on the "texlive" subpackage, but texlive-kpathsea doesn't actually depend on texlive, it's the other way around. texlive-kpathsea is at the top of the dependency chain. Moving these triggers to the kpathsea subpackage _should_ fix this. I'll do that in -8.

Tried rebuilding rdkit against -8, before I had:

I can't find the format file `pdflatex.fmt'!

now error is different:

just let me know if you would like another bug opened for this.

Nope. That is already open as https://bugzilla.redhat.com/show_bug.cgi?id=1383649 and -9 (which should fix it) is building now.

Seems better, but still having issues. The python-sphinx tests are fine in F24 and F25, but still fail in Rawhide against -12.

texlive is such a hot mess. -14 (building now) will have a "texlive-graphics-def" subpackage which includes luatex.def. I also made the texlive-luatex package depend on it.

This should resolve this failure. Thanks for your patience.

Errors in Sphinx tests with rawhide tex release -16

Seem to be further along, but still having issues. I'm a little lost when it comes to Tex, but it looks like most of the errors are undefined references related to "py@TitleColor" Is there a new dependency I should be including? Error log is attached.

Avram, this one has me stumped. Can you open an issue with Sphinx and see if they know what might be to blame here?

Tom, coincidently I just opened an issue this morning. They had an answer for me within an hour, so I'm guessing they've run into it before. Turns out I needed the texlive-luatex85 package with TexLive 2016. Seems to build and pass all the tests fine now.

I'm glad they were able to resolve it so quickly!
