pip install pgadmin4 fails on AWS Ubuntu image

[ShaheedHaque]

Description

Trying to pip install pgadmin4 on a recent AWS Ubuntu image (Ubuntu 24.04.1 LTS) fails with the following error:

ERROR: Exception:
Traceback (most recent call last):
  File "/home/ubuntu/venv/lib/python3.12/site-packages/pip/_internal/cli/base_command.py", line 105, in _run_wrapper
...
  File "/home/ubuntu/venv/lib/python3.12/site-packages/pip/_vendor/packaging/specifiers.py", line 28, in _coerce_version
    version = Version(version)
              ^^^^^^^^^^^^^^^^
  File "/home/ubuntu/venv/lib/python3.12/site-packages/pip/_vendor/packaging/version.py", line 202, in __init__
    raise InvalidVersion(f"Invalid version: '{version}'")
pip._vendor.packaging.version.InvalidVersion: Invalid version: '6.8.0-1014-aws'

The root of the problem seems to be the kernel image version, which is labelled like this:

$ uname -a
Linux ip-172-31-8-236 6.8.0-1014-aws #15-Ubuntu SMP Thu Aug  8 19:13:06 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

IIUC, the Python platform package uses uname to derive the platform.release.

Expected behavior

The pip command's Version class should not fail, and cause the installation to abort

pip version

pip 24.3.1

Python version

3.12

OS

Linux/Ubuntu on AWS

How to Reproduce

1. Launch an AWS Ubuntu image. I am using ubuntu/images/hvm-ssd-gp3/ubuntu-noble-24.04-amd64-server-20240827.
2. Login
3. pip install --break-system-packages pgadmin4

Output

$ pip install --break-system-packages pgadmin4

I should add that older versions of pgadmin4 install as follows, in the same environment.

pip install --break-system-packages 'pgadmin4<8.11'

Thanks for reporting, unfortunately this behavior comes from the vendored Packaging and this is a duplicate of: pypa/packaging#774

You can read the discussion there, but so far there hasn't been a consensus on how to resolve it.
