fontenc.sty broken line 115

Question

I've updated texlive this morning (2020-02-25 - 8.40 CET) and my documents, that compiled without trouble yesterday, report this error today:

/usr/local/texlive/2019/texmf-dist/tex/latex/base/fontenc.sty:115: Undefined co
ntrol sequence.
l.115 \xdef\@fontenc@load@list{\@fontenc@load@list

The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

It might be related to siunitx package (perhaps the command \micro), xelatex, fontenc, inputenc.

Right now, I don't have an MWE yet - hope that someone could help without it. If not, I'll edit tomorrow with an MWE.

Answer 1

fmtutil-sys (since a re-organisation last year) is part of texlive-scripts so

tlmgr install texlive-scripts

should make it available, and can then be used to rebuild the formats from the updated sources.

Answer 2

EDIT 1 Thanks to the (simultaneous) posts from @David Carlisle and @Ulrike Fischer the command tlmgr install texlive-scripts filled usr/local/texlive/2019/texmf-dist/scripts/texlive with the relevant scripts and now it looks like this:

END EDIT 1

So far I patched the original problem with great advice from the comments from @Ulrike Fischer:

I found out, that the directory usr/local/texlive/2019/texmf-dist/scripts/texlive no longer contained the files shell script fmtutil-sys.sh and the perl scripts fmtutil.pl and mktexlsr.pl. I copied those three over from my 2017 distribution, executed fmtutil-sys -all and ended up with this final result:

Transcript written on utf8mex.log.
fmtutil [INFO]: /usr/local/texlive/2019/texmf-var/web2c/pdftex/utf8mex.fmt installed.
fmtutil [ERROR]: running `mf-nowin -ini   -jobname=mf -progname=mf -translate-file=cp227.tcx mf.ini </dev/null' return status 1
fmtutil [ERROR]: return error due to options --strict

fmtutil [INFO]: Successfully rebuilt formats: 38
fmtutil [INFO]: Failed to build: 1 (mf-nowin/mf)
fmtutil [INFO]: Total formats: 44
fmtutil [INFO]: exiting with status 1

My original question above is at least workaround-patched, as my document compiles again. Therefore I dare to post this as an answer hoping, that it might be useful for someone else. Even it's not perfect.

In between I also tried to "Reinstall Tex Live Manager" from the GUI (in menu "Actions"), which did not help.

Note there are multiple other scripts missing in my 2019 installation compared to the 2017 installation - which might or might not kick in for someone else.

Answer 3

I had the same problem and suspect that it was due to some fonts I manually installed on my latex system. None of the previous answers worked for me and eventually I managed to fix it by deleting the ~/.texlive2019 folder and then running

sudo mktexlsr
updmap-sys --enable Map pfr.map
updmap-sys --enable Map sitdings.map

EDIT: I just saw @UlrikeFischers comment below OP's question. She said that the format in ~/.texlive2019/... was shadowing my system format and deleting it would solve the problem.
