Indeed, @INC contains /texmf-dist/scripts/texlive /tlpkg, which are
incorrect. The 2025 version of /usr/bin/tlmgr had:

  $Master = "/usr/share/texlive";
  $::installerdir = $Master;  # for config.guess et al., see TLUtils.pm

  # make Perl find our packages first:
  unshift (@INC, "$Master/tlpkg");
  unshift (@INC, "$Master/texmf-dist/scripts/texlive");

In the 2026, the

  $Master = "/usr/share/texlive";

line is missing.
