Raspberry Pi Bookworm - Fatal Python error: init_fs_encoding

[aluminum-ice]

I compiled ncpa from source into a debian package. No issues with the compilation. Installed the deb pacakge ncpa_3.1.0-1_arm64.deb without issue:

pi@raspberrypi:~/github/ncpa/build $ sudo dpkg -i ./ncpa_3.1.0-1_arm64.deb

Selecting previously unselected package ncpa.
(Reading database ... 124238 files and directories currently installed.)

Every attempt to start, stop or restart the ncpa service results in a python error:

I think the issue is with the (new) managed python package environment but every attempt to fix it fails. Any help or ideas?

Which specific python do you have? Primary issue above is the PYTHONHOME isn't defined. Could be a "cx freeze" issue, though. Which specific cx freeze version is installed?

Hi, this is what I see:

cx_freeze in /usr/local/lib/python3.11/site-packages (7.1.1)

I tried export PYTHONHOME=/usr/local/ but NCPA still reports the env variable as blank.
