Calibre 8.0.1 binary install error

[mathdaemon]

I'm trying to upgrade from 7.26 to Calibre 8.0.1 on Fedora 41.

~$ sudo -v && wget -nv -O- https://download.calibre-ebook.com/linux-installer.sh | sudo sh /dev/stdin

Using python executable: /usr/local/bin/python3
Traceback (most recent call last):
  File "<string>", line 1, in <module>
    import sys; script_launch=lambda:sys.exit('Download of installer failed!'); exec(sys.stdin.read()); script_launch()


  File "<string>", line 890, in script_launch
  File "<string>", line 837, in main
  File "<string>", line 788, in check_glibc_version
  File "/usr/local/lib/python3.13/ctypes/__init__.py", line 8, in <module>
    from _ctypes import Union, Structure, Array
ModuleNotFoundError: No module named '_ctypes'

Packages are present/updated and I've tried reinstalling python through dnf reinstall.
glibc version 2.40.

That error indicates the python you have installed in /usr/local is broken. Uninstall it and use the system python or fix it and you will be fine.
