Dear Jürgen,
thanks for the quick feedback.
It seems like the incompatibility occurred in one of the updates of units or
siunitx - before updating to the newest versions they could coexist.
Furthermore, nicefrac was used and thus units was required.
Your solution works fine! My document is now fully based on siunitx.
Kind regards,
Julian

LyX autoloads the package if you use a construct that requires this
package (e.g., \unitfrac, \unitfracthree, \nicefrac).

You can prevent autoloading by entering to Document > Settings > Local
Layout:
Provides units 1
But if you now have a LaTeX macro which requires this package (and is
not covered by siunitx), you'll get an "undefined control sequence"
error.
HTH,
Jürgen

Subject: Default usepackage units (LyX Default?) and user-specific siunitx
Dear LyX users,
I came across an (for me) unexpected behavior in LyX 2.3 that probably requires
me to change my whole document.
For typesetting units and values correctly, I used the package siunitx. Since I
got a new notebook and now have LyX 2.3.7 (+MiTeX) instead of 2.3.5-1 (in
addition to package updates) there is now an error about the incompatibility of
the packages units and siunitx. The issue here is: I do not have the
\usepackage{units} in my custom document preamble.
After some investigation I found out that LyX in nevertheless including the
\usepackage{units} in the LaTeX code (export -> LaTeX (pdflatex)). See code
below.
Has anybody else experienced that issue? Recommendations for mitigation?
BTW: uninstalling the package from MikTeX and removing the "units" entries in
.sty files in the LyX folder does not work :)
Thanks,
Julian
