Installation Issues with 'pip install unified-planning[engines]' on manjaro

[Core5563]

Describe the bug
When installing unified_planning (on Manjaro) on an virtual environment with the command
'pip install unified-planning[engines]'
the installation defaults back to unified-planning version 0.4.0
Trying to force version 1.1.0 with
"pip install 'unified-planning[engines]==1.1.0'"
gives the following errors:
ERROR: Ignored the following yanked versions: 0.0.1, 0.0.4.0, 0.0.4.1
ERROR: Could not find a version that satisfies the requirement up-lpg==0.0.10; extra == "engines" (from unified-planning[engines]) (from versions: none)
ERROR: No matching distribution found for up-lpg==0.0.10; extra == "engines"

To Reproduce
Steps to reproduce the behavior:
All done in one Terminal session:

1. make new project directory: mkdir unified-planning-test
2. go into project directory: cd unified-planning-test
3. set up virtual environment: python3 -m venv .venv
4. activate virtual environment: source .venv/bin/activate
5. install unified_planning: pip install 'unified-planning[engines]'
6. see version: pip list
   or
   steps 1. - 4. same as above
7. install unified_planning: pip install 'unified-planning[engines]==1.1.0'

Expected behavior
I expected the newest version with all available planners installed.

Screenshots
output of 'pip list' after "pip install 'unified-planning[engines]'":
Package Version

---

graphviz 0.20.3
networkx 3.3
pip 24.2
pyparsing 3.1.4
unified-planning 0.4.0

Desktop (please complete the following information):
OS: ManjaroLinux 24.1.1 Xahea
Python: Python 3.12.6

Additional context
The problem is probably somewhere with the LPG engine (package 'up-lpg').
if i install the planning engines separately with the commands:
pip install unified-planning[Fast-Downward]
pip install unified-planning[ENHSP]
pip install unified-planning[Tamer]
pip install unified-planning[Aries]
pip install unified-planning[Pyperplan]
then the correct version of unified planning is installed (albeit not with the lpg engine).
After that the output of 'pip list' is:
Package Version

---

ConfigSpace 1.2.0
grpcio 1.66.2
grpcio-tools 1.66.2
iniconfig 2.0.0
more-itertools 10.5.0
networkx 3.3
numpy 2.1.2
packaging 24.1
pip 24.2
pluggy 1.5.0
protobuf 5.28.2
pyparsing 3.1.4
pyperplan 2.1
pytamer 0.1.19
pytest 8.3.3
scipy 1.14.1
setuptools 75.1.0
typing_extensions 4.12.2
unified-planning 1.1.0
up_aries 0.3.4
up-enhsp 0.0.27
up-fast-downward 0.4.1
up-pyperplan 1.1.0
up-tamer 1.1.3
wheel 0.44.0

Additionally i tried 'pip cache purge' with no success.
Also installing up-lpg separately via git with "pip install ‘git+https://github.com/aiplan4eu/up-lpg’" did install up_lpg,
but after "pip install 'unified-planning[engines]'" the same behavior occurs.

@Core5563 Thanks for the report!

As you can see here, up-lpg is distributed for a limited number of python versions and architectures, in particular, they currently do not support python 3.12 (even though I expect there should be no issue in the source code to run on 3.12, hence installing manually from git seems to work).

@IvanSerina maybe you can add python 3.12 in the up-lpg distribution?
