I certainly did not update manually Miktex during the bundle3
installation. Read again my messages,
"To test this new installation program, I let the Miktex update run. I
have no idea what has been updated, but what's for sure is that the
compilations with LyX don't work anymore now ! "
This is what I don't understand. How could you decide to let the update
run on your own?
I realize now that you installed LyX 2.3.0 the first time using version
1 of the LyX installer. This can explain the problems you saw. I tested
this now but cannot reproduce.
Could you please maybe do me the favor and
- uninstall LyX and MiKTeX _completely_
- reinstall LyX using the 2.3.0 RC1/ installer (if you still have it on
- install LyX 2.3.0 over it using the version 3 installer.
I finally manage later to recover a working Miktex via the installation
of a new package.
This what i also don't understand. if MiKTeX is broken, you can try
whatever you want. Updates cannot be installed and a package
installation doesn't repair MiKTeX. There must have happened something
else. Because when a package update succeeds and you can use LyX
afterwards, then it could only happen that the package file name
database was incomplete.
However, I cannot reproduce this.
Meanwhile MiKTeX released 3 important bugfixes to its package handling
system. I hope that they are available tomorrow for all users.
