Hello,
Just tried it using the following commands:
apt update
apt install mercurial
hg debuginstall
checking encoding (utf-8)...
checking Python executable (/usr/bin/python3)
checking Python implementation (CPython)
checking Python version (3.12.3)
checking Python lib (/usr/lib/python3.12)...

checking Rust extensions (missing)

[...]
python3 --version
Python 3.12.3
Then, I used ubuntu-dev-tools to update to the latest python3.12.7:
apt install ubuntu-dev-tools
pull-lp-debs python3-defaults
pull-lp-debs python3.12
pull-lp-debs openssl
apt install ./python3_3.12.7-1_amd64.deb ./python3-minimal_3.12.7-1_amd64.deb
./libpython3-stdlib_3.12.7-1_amd64.deb
./libpython3.12-stdlib_3.12.7-3_amd64.deb
./python3.12-minimal_3.12.7-3_amd64.deb ./python3.12_3.12.7-3_amd64.deb
./libpython3.12-minimal_3.12.7-3_amd64.deb
./libssl3t64_3.3.1-2ubuntu2_amd64.deb ./libpython3.12t64_3.12.7-3_amd64.deb
I can confirm the bug:
hg debuginstall

AttributeError: partially initialized module 'threading' has no attribute
'RLock' (most likely due to a circular import)
Adding noble-proposed to sources and updating mercurial fixed the issue:
apt update
apt install mercurial/noble-proposed

python3 --version
Python 3.12.7
I can confirm the bug is solved using version 6.7.2-1ubuntu2.2
