📝 Provide a clear and concise description of the issue.

After fully installing the Flaresolverr LXC using the provided script, the flaresolverr service does not start due to the following error:

[PYI-3667:ERROR] Failed to load Python shared library '/opt/flaresolverr/_internal/libpython3.13.so.1.0': /lib/x86_64-linux-gnu/libm.so.6: version GLIBC_2.38' not found (required by /opt/flaresolverr/_internal/libpython3.13.so.1.0)`

It seems to be looking for Python 3.13 libraries, though the installed Python version is 3.11.2. My ldd version is 2.36.

🔄 Steps to reproduce the issue.

  1. Use the provided bash command to install the flaresolverr lxc
  2. try to run the flaresolverr service (directly with ./opt/flaresolverr/flaresolver or using systemctl daemon)

❌ Paste the full error output (if available).

Seems Like there prebuild file is build with an newer system then Debian 12, so Its have another glib.

Please Report in there repo and ask why. (all downward compatibility is broken)

The latest Flaresolverr (v3.4.0) requires python 3.13 while the debian12 template is on python 3.11
