Well, the scripts run without issues, but No, they did not work to fix the problem.

    5 days later

    Do you have ffcall installed, if not, can you try if adding it helps? It is a makedepends now, but seems should be made a depend.

    I installed it and reinstalled tex-live (bin, core, latexextras) and kile, and still the same issue

    16 days later

    This morning I've freshly re-installed Kaos, including all tex and latex packages from the main app list.
    When compiling a test.tex doc, there were problems with latex and pdflatex (wrong /etc/texmf/web2c/fmtutil.cnf file or missing config file?).

    `$ pdflatex test.tex
    This is pdfTeX, Version 3.14159265-2.6-1.40.20 (TeX Live 2019/KaOS) (preloaded format=pdflatex)

      Merged 1 post from latex/pdftex unable to make .fmt files.

      thomaslemmens merged it with existing texlive thread, so far no known fix for this bug.
      All I can do is upload all texlive packages from 2018, see if it is an issue with the 2019 versions only.

      sudo pacman -U https://sourceforge.net/projects/kaosx/files/packages/texlive-bin-2018.47465-10-x86_64.pkg.tar.xz https://sourceforge.net/projects/kaosx/files/packages/texlive-core-2018.47471-2-x86_64.pkg.tar.xz

        man fmutil says:

        Otherwise, fmtutil
        reads all the fmtutil.cnf files found by running `kpsewhich -all fmtutil.cnf', in the order returned by kpsewhich.<

        So, in the shell:

        kpsewhich -all fmtutil.cnf
        /etc/texmf/web2c/fmtutil.cnf
        ``
        The returned config file has only outcommented lines.

        Hope this helps in solving the issue.

        Please try only texlive-core first, looks like the issue should be there.

        After downgrading to the 2018 version pdflatex compiled as expected without errors.

        In the terminal:

        kpsewhich -all fmtutil.cnf
        /etc/texmf/web2c/fmtutil.cnf
        /usr/share/texmf-dist/web2c/fmtutil.cnf

        The first returned config file looked identical as in the 2019-version (only outcommented lines).
        The second is missing in the 2019-version and is the actual config file fmtutil needs in making texformats

        • demm replied to this.

          After backing up the second config file, I upgraded to the actual version which returned a broken system again. After copying the backed up config file to /etc/texmf/web2c (/usr/share/techmf-dist/web2c/fmtutil.cnf was not returned by kpsewhich -all fmtutil.cnf and the replaced config file in /etc/texmf/web2c only had outcommented lines) and after deleting the .texlive map in /home/user, the 2019 tex system worked as expected (without errors). The /home/user/.texlive map had to be deleted since there existed format files constructed by fmtutil from the 2018 version (>resulted in errors).

          Maybe a somewhat 'cleaner' repair is to copy the backed up file to /usr/share/techmf-dist/web2c/ . But since kpathsea cannot find this newly inserted (was missing) config file, you have to complete the ls-R database. The command mktexlsr (as root!) is used to generate the ls-R databases used by the kpathsea library. It will create them for the specified directories, or for a default list if no directories are specified.

          So it is my understanding that it is just texlive-core.

          3 months later

          The downgrade of texlive-core and bin to 2018 version worked for a while. However since an update a bit more than 1 month ago (before the Covid-19 lock-down), this downgrade stopped working. Now either the new 2019 nor the 2018 version work. Is there an actual solution for this problem that you can point me at? My work depends on this and I am tired of using another distro in another machine to generate my document files. Thanks in advance.

          Since I'm not a texlive user, I fully depend on reports from you guys to figure a solution. So far I have nothing to go on what the issue might be in texlive 2019. 2020 is out, so I can try and see if updating to that version helps, but without knowing what caused the regression, I think that would be a slim chance.

          Here latex and kile are working fine. (I'm in build).

          Kamilomelo, can you make some tiny test.tex script, compile it in the terminal
          pdftex test.tex
          and publish here the (terminal) output?

          Sure @thomaslemmens here is the script:

          \documentclass[a4paper,10pt]{article}
\usepackage[utf8]{inputenc}
%opening
\title{Test}
\author{Kamilomelo}
\begin{document}
\maketitle
This is a test text
\end{document}

          And here the output:

          $ pdftex test.tex 
This is pdfTeX, Version 3.14159265-2.6-1.40.20 (TeX Live 2019/KaOS) (preloaded format=pdftex)
 restricted \write18 enabled.
---! /home/kamilo/.texlive/texmf-var/web2c/pdftex/pdftex.fmt made by different executable version
(Fatal format file error; I'm stymied)

          Delete the /home/kamilo/.texlive map since this map is containing format files constructed by fmtutil from an earlier version, probably the 2018 version. (You can first make a backup of this map if you wish so)

          Then retry to compile your test.tex and if this results in errors post the log file here.

          P.S. I'm going to sleep now. Hope to be there again tomorrow.

          Here the output:

          $ pdftex test.tex

kpathsea: Running mktexfmt pdftex.fmt
mktexfmt: mktexfmt is using the following fmtutil.cnf files (in precedence order):
mktexfmt:   /etc/texmf/web2c/fmtutil.cnf
mktexfmt: mktexfmt is using the following fmtutil.cnf file for writing changes:
mktexfmt:   /home/kamilo/.texlive/texmf-config/web2c/fmtutil.cnf
mktexfmt [INFO]: writing formats under /home/kamilo/.texlive/texmf-var/web2c
mktexfmt [INFO]: did not find entry for byfmt=pdftex, skipped
mktexfmt [INFO]: Total formats: 0
mktexfmt [INFO]: exiting with status 0
I can't find the format file `pdftex.fmt'!

          The 2019 version of tex is missing a config file needed by fmtutil to generate format files.
          So you have to reconstruct this file in this manner:

          First: open a terminal for the following command:
          sudo nano /usr/share/texmf-dist/web2c/fmtutil.cnf
          This will open a new empty file.

          Second: Copy and paste this content into this newly opened file (I have taken this from the tex2018 package where this file was not missing):

#$Id: fmtutil-hdr.cnf 37176 2015-05-04 02:06:19Z preining $
#Originally written by Thomas Esser, 1998. Public domain.
#
#As of TeX Live 2015, fmtutil reads *all* fmtutil.cnf files found.
#Consequently, any manual edits of this file (fmtutil.cnf in the 
#TEXMFDIST tree) will be lost on update. So don't do that.
#
#For guidance on how to achieve local configurations, see the man
#page of fmtutil, or the output of fmtutil --help.
#
#The format of the table is:
#
#format  engine  pattern-file  arguments
#
#The last "argument" must be the name of the file on which to run
#the ini-engine (such as initex).  If the ini-engine is e-TeX, and the
#e-TeX extensions should be enabled, the filename must be prefixed with
#a * character; this is essentially equivalent to the -etex option.
# 
#fmtutil always passes the -ini option to the engine.
#If no pattern-file is desired, use -.
#Either spaces or tabs can be used as separators.
# 
#Other notes:
#1) tex and amstex just load hyphen.tex. No customization.
#You can have your own customized (via babel's hyphen.cfg)
#formats on top of plain by using "bplain.tex" instead of
#plain.tex (e.g., bplain.ini file for bplain format).
#
#2) etex-based formats load language.def, not language.dat.
#
#3) The symbolic link to the right engines (e.g. bplain -> tex)
#is generated by the "texlinks" script.
# 
#4) usual comments start with "# ", whereas disabled configurations
#start with "#! " in this file.

          Three: Save this file to disk. This will reconstruct the missing configuration file in tex2019.

          Four: Now you have to complete the ls-R database, otherwise tex does not know about the newly created file.
          The command mktexlsr (as root!) is used to generate the ls-R databases used by the kpathsea library. It will create them for the specified directories, or for a default list if no directories are specified. The default list is sufficient here.
          So in the terminal:
          sudo mktexlsr

          Five: Compile your test.tex file. It should compile fine now.
