Absurd dependencies

Writing something in texinfo, it happens that I can’t use @subentry for the index. It seems Ubuntu 19.10 has an old texinfo. So I downloaded the latest and wanted to purge the old one. But:

$ sudo apt-get remove texinfo
[sudo] password for user: 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
...
The following packages will be REMOVED:
  cantor-backend-octave dynare liboctave-dev lilypond lilypond-data matlab2tikz octave octave-bim octave-biosig octave-bsltl
  octave-cgi octave-communications octave-communications-common octave-control octave-data-smoothing octave-dataframe octave-dicom

  octave-symbolic octave-tsa octave-vibes octave-vlfeat octave-vrml octave-zenity octave-zeromq texinfo texlive-full

Why? Why removing texinfo should bring down the whole texlive-full and whole pieces of octave and… WTF. Idiotic, nonsense dependencies.

So I will keep that old texinfo. And Ubuntu has one more angle to push me towards their personal nightmare (I mean, snaps).
