MiKTeX: File hyperref.cfg is missing

Question

After updating my MiKTeX-Installation (dated 2020-01-29) I am unable to compile my LaTeX-files.

Here is my MWE:

\documentclass{article}
\usepackage{hyperref}
\begin{document}
\href{www.google.com}{Google}
\end{document}

If i try to compile this using pdflatex Test.tex I get the following output on the command line:

...
...
("C:\Program Files\MiKTeX2.9\tex/generic/intcalc\intcalc.sty")
("C:\Program Files\MiKTeX2.9\tex/generic/etexcmds\etexcmds.sty")

After a while the MiKTeX Package Installation dialog box pops up with the following message:

The required file
  tex/latex/00miktex/hyperref.cfg
is missing. It is part of the following package:
  miktex-latex

After clicking Install the output on the command line continues with

======================================================================

package repository: C:/Installation/LaTeX/MiKTeX/Repository

======================================================================

Sorry, but pdflatex did not succeed.

The log file hopefully contains the information to get MiKTeX going again:

  C:\Users\xxxx\AppData\Local\MiKTeX\2.9\miktex\log\pdflatex.log

The log-files contains the following:

INFO  pdflatex - starting with command line: pdflatex Test.tex

FATAL pdflatex - The installed file does not exist.

Interestingly the repository file miktex-latex.tar.lzma contains only 3 files, namely:

texmf/tex/latex/00miktex/latex.ini
texmf/tex/latex/00miktex/pdflatex.ini
texmf/tpm/packages/miktex-latex.tpm

In an older repository version (2020-01-21) which I still have there are 4 files in miktex-latex.tar.lzma:

texmf/tex/latex/00miktex/hyperref.cfg
texmf/tex/latex/00miktex/latex.ini
texmf/tex/latex/00miktex/pdflatex.ini
texmf/tpm/packages/miktex-latex.tpm

So obviously MiKTeX tries to install / update a file hyperref.cfg which supposedly should be in miktex-latex.tar.lzma. But since 2020-01-22 it isn't there anymore.

I also tried with a complete new clean install of MiKTeX but with the same result.

BTW, using the repository dated 2020-01-29 makes it necessary to apply Ulrike's solution from File hycolor.sty not found

Answer 1

The problem can be solved by updating the package database using Tasks / Update package database and Tasks / Refresh file name database.

Credits for the solution go to "daleif". Thanks.
