We need a little more detail than that :)
Post the full console output of Buildozer, as a text file.
Probably a good idea to post whatever configuration is used, post the buildozer.spec
A good test for you to try is to delete the project/.buildozer directory and rename buildozer.spec to something else. Now run "buildozer init" again
Then the test is to then try the buildozer build without changing anything in the .spec file (really nothing). This is just a test to see if you get the same error.
