hostpython3 unpack error

[onsunsl]

Versions

• Python: 3.6.9
• OS: ubuntu18.04 64bit
• Kivy: 1.11.1
• Cython: 0.29.15
• OpenJDK: 1.8

Description

My ubuntu host comes with python version 3.6.9, and I also specified 3.6.9 in the.specfile. Why should download python3.8.1 when buidozer running? And the error is reported during unpack

buildozer.spec

#    List as sections
#
#    You can define all the "list" as [section:key].
#    Each line will be considered as a option to the list.
#    Let's take [app] / source.exclude_patterns.
#    Instead of doing:
#
#[app]
#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*
#
#    This can be translated into:
#
#[app:source.exclude_patterns]
#license
#data/audio/*.wav
#data/images/original/*
#


#    -----------------------------------------------------------------------------
#    Profiles
#
#    You can extend section / key with a profile
#    For example, you want to deploy a demo version of your application without
#    HD content. You could first change the title to add "(demo)" in the name
#    and extend the excluded directories to remove the HD content.
#
#[app@demo]
#title = My Application (demo)
#
#[app:source.exclude_patterns@demo]
#images/hd/*
#
#    Then, invoke the command line with the "demo" profile:
#
#buildozer --profile demo android debug

I think your download simply got corrupted, delete that file and try again /home/kivy/test/.buildozer/android/platform/build-armeabi-v7a/packages/hostpython3/Python-3.8.1.tgz

Thank AndreMiras‘ answer.
I tried to download Python-3.8.1.tgz twice manually, and copying to /home/kivy/test/.buildozer/android/platform/build-armeabi-v7a/packages/hostpython3, but all got same error.

I tried to modify requirements.source of .spce file for below:

# (list) Application requirements
# comma separated e.g. requirements = sqlite3,kivy
requirements = hostpython3==3.6.9,python3==3.6.9,kivy,six==1.12.0

# (str) Custom source folders for requirements
# Sets custom source for any requirements with recipes
# requirements.source.kivy = ../../kivy
requirements.source.hostpython3 = ../requirements_source/Python-3.6.9
requirements.source.python3 = ../requirements_source/Python-3.6.9
requirements.source.libffi = ../requirements_source/libffi-8fa8837
requirements.source.openssl = ../requirements_source/openssl-1.1.1f
requirements.source.sdl2_image = ../requirements_source/SDL2_image-2.0.4
requirements.source.sdl2_mixer = ../requirements_source/SDL2_mixer-2.0.4
requirements.source.sdl2_ttf = ../requirements_source/SDL2_ttf-2.0.14

And then catch an other error：

Is this a bug of p4a? Wath should i do?
Thanks all.

I tried to download Python-3.8.1.tgz twice manually, and copying to /home/kivy/test/.buildozer/android/platform/build-armeabi-v7a/packages/hostpython3, but all got same error.

Nice that you tried. I would say in this case the best is to try from the shell and also give some info about the file that was downloaded by p4a. So you can do multiple things to help understanding what's going on. First is to check what file is this if it's not a tar archive.

file /home/kivy/test/.buildozer/android/platform/build-armeabi-v7a/packages/hostpython3/Python-3.8.1.tgz

If it says text, then you can inspect it directory with a text editor. And share the info here or try to debug further yourself until it all makes sense. In the mean time when you see that type of bug, you can also try to reproduce entirely from the shell, meaning downloading yourself and running the tar command. In the same way you should provide as much as info as possible to help debugging. So for instance trying to download from the shell and then extract and again if it doesn't work inspect the file with file and other commands. So for instance:

wget https://www.python.org/ftp/python/3.8.1/Python-3.8.1.tgz
file Python-3.8.1.tgz
tar --version
tar xf Python-3.8.1.tgz

The more info we get the better we can help debugging. Also don't be afraid to dig further yourself, specially if it's an issue that we cannot reproduce ourselves. So dig into it, put some breakpoints, make hot fix/workaround to the code until the problem get more clear

Thanks AndreMiras.
Thank you very much for your answers. I am a beginner, and your suggestions give me great encouragement.
I will try id according to your suggestion immediately, and synchronize thre result on here.

In addition, some web site access in here is restricted, such as google.com. Some sites such as github.com ， python.org are not restricted, but the nework speed is very slow. so I tried vpn proxy access them, I has set up the ubuntu proxy, and also in the brower can access google.com normally, but running buildozer command to download is still very slow.

I don't know why, maybe the proxy config are not effective.
Sorry, my English is poor, there may be errors in the expression grammar.

[onsunsl]

1.Modify .spce file requirements: python==3.6.9, hostpython==3.6.9
2.Re-download Python3.6.9-3.6.9.tgz to /home/Download (download manually by brower, buildozer download very slow, maybe the proxy config are not effective )
3. run command with below:

cd /home/kivy/Download
rm /home/kivy/test/.buildozer/android/platform/build-armeabi-v7a/packages/hostpython3/*
rm -rf /home/kivy/test/.buildozer/android/platform/build-armeabi-v7a/packages/hostpython3/*
cp Python-3.6.9.tgz /home/kivy/test/.buildozer/android/platform/build-armeabi-v7a/packages/hostpython3/Python-3.6.9.tgz
cp Python-3.6.9.tgz /home/kivy/test/.buildozer/android/platform/build-armeabi-v7a/packages/hostpython3/.mark-Python-3.6.9.tgz 
rm -rf /home/kivy/test/.buildozer/android/platform/build-armeabi-v7a/build/other_builds/hostpython3/

• hostpython can be successfully unpack. but I don't kown why it is necessary to include the .mark-Python-3.6.9.tgz and Python-3.6.9.tgz files. If there is no .mark-Python-3.6.9.tgz file , the Python-3.6.9.tgz package will be deleted and re-downloaded.

• Got SDL2_image source path can not found error in log.
  Because my .spce file specifiles SDL2, SDL2_image, SDL2_ttf, SDL2_mixer requirements source directory at the same time. some modules will be lost. Because they are save to the same directory SDL2 and each time they are unpacked. the entire directory is deleted and recreate.

Yes don't try with Python 3.6 as we no longer test against it. Stick to 3.8.1 which is the default p4a one.
Why don't you share the log/trials of the command I shared earlier.
And indeed if your network is slow then it makes sense, it might well be it. What I would do is to indeed double check with the commands I shared and then yes try to download yourself manually, eventually also using the -c flag of wget for resuming. But yes if you have slow/blocked network, you will have hard time going through all of this

After adding the -c option with wget, the download speed is very fast 2.26MB/S, and it will downloaded later. it is unpack success.

Wath do i need to do to increase the download speed in buidozer command.
