Because you requested a mixture of 2025 and 2024 packages.  This is 
clearly visible in the Resolving Dependencies box.

It's going to be a while until I have time to look at all the 
attachments.  In the meantime, you could try to diagnose the problem 
yourself.  I would start by trying to figure out why the postinstall 
scripts are failing.  There might be helpful error messages in 
setup.log.full.  Alternatively, try to run the scripts manually, as the 
same user that runs the setup program.  Run the commands in them line by 
line if necessary.  Also check to see if any of the preremove scripts 
are failing, and try to figure out why.

If this doesn't help, try again to install TeX Live 2024, this time 
picking the 2024 versions of all relevant packages.  The Resolving 
Dependencies box will tell you if you're still trying to install some 
2025 packages.

If you still get postinstall/preremove scripts failing, you might have 
to completely remove TeX Live from your system and start from scratch. 
Don't forget to look at /var/lib/texmf, /etc/texmf, /usr/share/tlpkg, 
and /usr/share/texmf*, and remove them manually if necessary.  I hope I 
haven't forgotten anything.

Ken
