Could you please provide more context? A MWE, the log file, the versions of packages (most important se2thesis), etc.?

I can tell that with se2thesis 4.4.0, which is available on CTAN since 2024–04–21, and TeX Live 2026, this error does not occur, see the attached log file.

I have no idea, which versions Ubuntu bundles, but probably some outdated ones. If you want to have a TeX Live that “just works”, consider building your image upon the ones from Island of TeX. They provide TeX Live images for current and history versions, updated once a week.

The code you are using will use se2thesis that comes with Ubuntu's TeX Live, which oughts to be TL2024, i.e. an ancient version (in terms of current speed of TeX developments...). If you want to make sure that you have at least the latest version of se2thesis running, you could use the l3build tool—this package provides you the respective build file; l3build install will install se2thesis into $TEXMFHOME, cf. the tool's documentation for more details.

Beware that just installing se2thesis into $TEXMFHOME of this old TeX Live 2024 provided by Ubuntu might not solve the issue or cause even more headaches! Always use a recent TeX Live (or at least one that was released after se2thesis' release date, i.e. TL2025 in this case, to make sure that also all dependent packages' versions are suitable).

I am closing this (and #24) because it is most likely caused by outdated software.
