Core26: bundled Python changes

[TehAppKiller]

oHi @mr_cal ,

Thanks for the explanations.

I updated to Snapcraft 9.0-RC

• 1/ With python runtime defined before app,

Same building problem where it cannot find python in 2nd part:

parts:
  python-runtime:
    plugin: nil
    stage-packages:
      - python3
      - python3-venv
      
  bazarr:
    after:
      - python-runtime
    plugin: python

Output:

• 2/ with python3-minimal, of course, same problem:

parts:
  python-runtime:
    plugin: nil
    stage-packages:
      - python3-minimal
      - python3-venv

• 3/ adding python3.14-minimal explicitly defined, it builds without error or warning:

parts:
  python-runtime:
    plugin: nil
    stage-packages:
      - python3-minimal
      - python3.14-minimal
      - python3-venv

but as python3.14-minimal is a dependency required by python3and python3-minimal, there seems to be a deeper problem there.

AND we’re now forced to define python version, if it stays this way.

• but it does NOT run

The modules from requirements.txt are present in the snap libs but not loaded

• 4/ same thing with whole definition from example:

parts:
  python-runtime:
    plugin: nil
    stage-packages:
      - libpython3.14-minimal
      - libpython3.14-stdlib
      - python3-minimal
      - python3.14-minimal
      - python3.14-venv

builds but does NOT run ; modules NOT loaded.

• 5/ it runs with python3 + python3-venv + python3.14-minimal definition:

parts:
  python-runtime:
    plugin: nil
    stage-packages:
      - python3.14-minimal
      - python3
      - python3-venv

• 6/ it builds with python3.13 from deadsnakes ppa but fails to run (no module found even pip)

  python-runtime:
    plugin: nil
    stage-packages:
      - python3.13
      - python3.13-venv

the python version must be defined in build-environment or it uses python 3.14 ; not sure if this is expected (?)

    build-environment:
      - PARTS_PYTHON_INTERPRETER: python3.13

• Both my snaps bazarr-tak (used for my tests) and flaresolverr-tak using python plugin are working with core26 and snapcraft 9.0-rc now.

Thx <3

Update:

It doesn’t work with a different python version

[TehAppKiller]

After a night of thoughts, my guess was that python from stage-packages affected python from snapcraft.

• So I ran a test:

1/ [Test1] check python version and modules

2/ load python runtime stage-packages

3/ [Test2] check python version and modules

4/ build app with requirements

5/ [Test3] check python version and modules

parts:
  test:
    plugin: nil

      python3 -V
      pip list

      - test
    plugin: nil
    stage-packages:

      then
        new_snap_version="${src_version}";
      else
        # Get snap build version
        snap_build=$(echo $snap_build_with_same_version | sed -nre 's/^.*-v([0-9]*).*/\1/p');
        # Already a build version ?

        then

        else
          # increment @v+1
          new_snap_build=$(($snap_build+1));
        fi

        new_snap_version="${src_version}-v${new_snap_build}";
      fi

       craftctl set version=$new_snap_version

      # Build
      INST_DIR="$CRAFT_PART_INSTALL/Bazarr"
      mkdir -p "$INST_DIR"
      cp -a ./* $INST_DIR
      
      craftctl default
    build-packages:
      - curl
      - wget
      - unzip
      
  test3:
    after:
      - bazarr
    plugin: nil
    override-build: |
      python3 -V
      pip list
      craftctl default

• It results that snapcraft python is affected by this ; with different modules and different modules versions:

Wouldn’t it be problematic for the other parts of snapcraft that uses python ?

Snapcraft now uses python3.13 (and fails to find even pip).

Info:

I edited my previous post ; with python3.13 it builds but does NOT run (no modules loaded even not pip)

[mwb]

I noticed @lengau published Install python-runtime-core24-312 on Linux | Snap Store

I think it would be awesome if there would be python snaps where we could ‘depend’ on; my company is using multiple different python based snaps and we’d prefer not to balloon every one snap with their own python.

Is someone (maybe at canonical, such as @lengau, who obviously experimented with it) picking this up? Otherwise I guess we ourselves would at least privately publish python 3.10, 3.12 and 3.14. If there’s more interest maybe we can publish all recent pythons across core24 and core26 publicly.

@mwb

I noticed @lengau published Install python-runtime-core24-312 on Linux | Snap Store

It’s certainly feasible to do (that’s what my experiment was about), but we don’t currently have capacity on the correct teams to pick it up officially. I would be happy to help work on content snaps like this, but it would only be in a personal capacity.

oHi,

I tried with stable Snapcraft 9.0.0 (rev. 18124) and core26 20260531 (rev. 409).

• venv is still not hermetic with other parts of the snap during build
• case A: same python libs than snapcraft ones: does NOT build
• case B: different python libs version than snapcraft ones: does NOT build

Same tests than before:

• Case A (python 3.14):

Building test3
:: + python3 -V
:: Python 3.14.4
:: + pip list
:: Traceback (most recent call last):
::   File "/root/stage/bin/pip", line 5, in <module>
::     from pip._internal.cli.main import main
:: ModuleNotFoundError: No module named 'pip'

• Case B (python 3.13):

Building test3
:: + python3 -V
:: Python 3.13.14
:: + pip list
:: Traceback (most recent call last):
::   File "/root/stage/bin/pip", line 3, in <module>
::     from pip._internal.cli.main import main
:: ModuleNotFoundError: No module named 'pip'

Thanks.

Edit:

When snap is built with case A (= no test3 performed), python modules are not loaded when running the snap.

Description:

Here is a proof-of-concept – not a reference, and there must be proper way to do it – on how to have a working python plugin.

Problems:

• 1/ For now, the python plugin messes with python environment provided with snapcraft.
• 2/ With core26 and snapcraft 9, the plugin doesn’t pack the snap properly anymore and modules are not loaded both for python runtime using same version than the one used by snapcraft (was working somehow before) and for runtime using a different version (was not working before).

Postulates:

• For the build of a snap, Snapcraft, some of its plugins and extensions, require the python runtime and environment they come provided with ; thus, a virtual environment (a.k.a. venv) seems to be required not to mess with it for the python plugin
• A venv is currently declared but never activated or used
• My guess is that a snap can come with only 1 python runtime and 1 environment. If it’s not the case it would greatly complicate the task: is it possible to run several apps/daemons with different runtime within a snap? may need to copy and adapt the venv locally to avoid readonly? may need to know which runtime&venv to use with each app/daemon? …

What it is not:

This post does NOT treat about:

• How to package this for a smooth user experience ; possible with a plugin only ? requires an extension ?..
• What source should provide python runtime(s) not available in default repositories ? and how to specify it ?
• How to manage conflicts in module dependencies for different parts using the python plugin
• How to make manual change properly in the venv for custom override-build ; requires activation/deactivation ; not sure it can be transparent to the user to avoid problems

Proof of concept:

• snapcraft.yaml
