[quitegreensky]

I have this problem too . Don't know thy this happens

[AndreMiras]

We don't have enough logs to tell. We need full log and buildozer.spec file. Also code needs to be formatted (use grace accent/backquote) to be read properly

[suvidh]

I am facing the same issue.
The issue persists regardless of what I add to buildozer.spec

WIndows 10:
Using it on WSL ubuntu

[stefan-sherwood]

This happens because you are attempting to set permissions on files on mounted Windows drives from WSL, which is prohibited due to incompatibilities between Windows file permissions and Linux file permissions.

The function that is failing, copytree(), attempts to apply permissions to copied files, hence the Permission Denied error.

You can remedy this by building from a directory that is relative to the WSL root, e.g. ~/myProject

please, how?

[stefan-sherwood]

I explained how. Please use more words to describe what you don't understand about the solution I suggested.

[al-chris]

This I what I'm currently facing

[al-chris]

I explained how. Please use more words to describe what you don't understand about the solution I suggested.

I am building from ~/camera and getting:
PermissionError: [Errno 13] Permission denied: '/home/alchris/camera/main.py'

[stefan-sherwood]

Thanks for the clarification. What do you see if you type ls -l /home/alchris/camera/main.py?

[stefan-sherwood]

Also, strange that it's getting the error when opening the file, not when actually copying it. You can add this log statement in /usr/lib/python3.8/shuil.py just before line 261 print( f"{src=}, {dst=}" ) to get more clarity.

[SomyKamble]

Permission denied by Kivy at the very last stage of the build compile

: shutil.Error: [('/mnt/d/kivy_projects/basics/.buildozer/applibs', '/mnt/d/kivy_projects/basics/.buildozer/android/app/_applibs', "[Errno 13] Permission denied: '/mnt/d/kivy_projects/basics/.buildozer/android/app/_applibs'")]

Can anyone please help

[stefan-sherwood]

@SomyKamble I described the cause and a workaround for the problem in my first comment.

[hladkky]

@stefan-sherwood Hello. I am facing the same issue.
As you recommended, I create ~/app directory and I have tried to build from there, but have got this error.

But I have got this file in my project root folder. What should I do?
Should I create the same file on the WSL, or someway give a route to the application root?

[stefan-sherwood]

As shown in your screenshot, it's trying to set permissions on a file whose root is /mnt/d. That is a Windows directory. You cannot build projects located in a Windows directory. Move it to WSL and try again.

[hladkky]

In what way can I totally copy application root folder to WSL? And the same question for returning apk, that will have been built there.

[hladkky]

@stefan-sherwood I have started building, but at the very end got this error:

Where can I check logs?

[stefan-sherwood]

Unfortunately the error is not shown. Try executing the exact command that comes after "Command failed: " and paste here what it says in response.

[hladkky]

This is a response of command. But this module has to be installed...

[hladkky]

After installing this package, I have got the same error, and after trying to debug got this:

[stefan-sherwood]

The second one is a different error and it says exactly what the problem is 😮

[hladkky]

Well, what the solution could be?
I have followed buildozer installation steps for Ubuntu 20.04, given here: https://buildozer.readthedocs.io/en/latest/installation.html
After that:
buildozer init -> rewrite buildozer.sped -> buildozer android debug deploy run

[stefan-sherwood]

If you Google the error message then the answer comes up as the first result. I am not going to debug your whole application, especially if you don't demonstrate diligence in figuring it out yourself.

[myNameIsHamza]

Permission problem probably from using root(sudo -s) while typing commands!

[bycellatt]

Do sudo su. Install the buildozer later

[skorpions2000]

Nothing changed and I have this mistake ... What happened? With sudo -s is working... What caused this error? Ten minutes earlier everything worked without root (sudo -s)

[Uni-Creator]

@hladkky
Fixed by installing libtool.

sudo apt-get install -y libtool

Based on first post where Python complains that it cannot access directory:

shutil.Error: [('/mnt/f/helo/.buildozer/applibs', '/mnt/f/helo/.buildozer/android/app/_applibs', "[Errno 13] Permission denied: '/mnt/f/helo/.buildozer/android/app/_applibs'")]

So your project is inside F:\helo\ at Windows side.

Just grant full control access to folder F:\helo\ at Windows to your current Windows user.

If your "WindowsUsername" is not listed in your directory properties, click Edit button and add it first.

[stefan-sherwood]

Just grant full control access to folder F:\helo\ at Windows to your current Windows user.

This is incorrect. As I explained above here you cannot grant a WSL full permissions to a non-WSL folder.

[Marcinosoft]

You're wrong. Wanna proof of my Windows setup? I faced exactly same issue yesterday.

PS. I just reproduced it twice. Windows user require full access control to be able to pass shuil.py copy under Linux (in my case Ubuntu 20.04 LTS) by buildoizer. It may be significant, that I'm using WSL version 1 (not version 2). Why I'm using WSL v1 ? Because v2 require additional virtualization Windows features which are not compatible with Nox Android Emulator for example. How to switch between WSL 1 and 2 ?

wsl --set-default-version 1
wsl --set-default-version 2

[stefan-sherwood]

this buildozer line will fail if the libraries are being copied from Windows to WSL. This is identical behavior in WSL 1 and 2.

What are the file paths being used in the copytree() call for you?

[Marcinosoft]

Ok, short story long.

In my case I placed project within:
C:\Kivy\Project\
I could create Kivy folder on root C: drive because I am member of Administrator group, which gives me indirectly Full control permission. But regular users by default have got: Read, Read & Execute, List folder content and Write. My user is an owner of C:\Kivy\ and everything inside of it to be clear. Permissions for nested objects are inherited from parents.

Then we have Ubuntu Linux (WSL) process, running under my Windows user. My user as I wrote before is part of Administrators group, but in Windows my user does not act as admin by default. It acts like regular user first, then if something require admin rights, then it's able to request additional rights, which usually require human confirmation (behaviour can be changed at UAC account setting).

Ubuntu Linux is able to operate on Windows folders because they are mounted as /mnt/?/, where ? is Windows drive letter, like c in my case. Ok, so under Linux I can operate on /mnt/c/Kivy/Project/ same as C:\Kivy\Project\ under Windows. When I create a file within /mnt/c/Kivy/Project/ folder, it will produce the same result like file created under Windows.

But when Linux world want to do something, which Windows user running wsl process cannot do directly, It can't invoke Windows behaviour which asks human to agree to do such operation as administrator. Linux always operate on Windows mounted file system based on regular, direct user rights.

That's why Buildozer launched under Linux is able to download and store over 1.3GB content within '/mnt/c/Kivy/Project/.buildozer/' without permission errors. At this phase regular users rights are enought. But copytree() require something more at Linux, and also Windows side. That's why it ends with [Errno 13] Permission denied: '/mnt/c/Kivy/Project/.buildozer/android/app/_applibs'.

copytree() under Linux invokes file permission operations (duplicating) at Windows side, which is allowed with Full control only.
When I granted it to C:\Kivy\ folder for my user, then no more admin right was required. Windows do not need to ask human to agree rights escalation. It directly have permissions to manage file rights under Windows, that's why copytree() under Linux succeed.

It's similar to this: https://stackoverflow.com/questions/11835833/why-would-shutil-copy-raise-a-permission-exception-when-cp-doesnt

If someone would ever wonder, you can open root WSL directory on your windows by typing "cd ~" in ubuntu and next typing "explorer.exe . "

[MariwanJ]

@Marcinosoft
Thank you very much . You saved my time and you knew the solution. But, if this not working for you please try to know if you are missing other libraries.
I have Windows 10, and Ubuntu VM - you shouldn't use root to run buildozer

[Mishabich42]

sudo chmod +x /root/.buildozer/android/platform/android-sdk/tools/bin/sdkmanager
sudo chmod -R 755 /root/.buildozer/android/platform/android-sdk
