This is a missing system dependency, install it and the other and you will be fine.
You have the support channel on discord for supoort questions

[sujeeth30]

Can you please tell me what are those dependencies I have to install?

[AndreMiras]

With the ones listed in the Dockerfile it's a good start:
https://github.com/kivy/buildozer/blob/831d85a/Dockerfile#L45
For instance you see autoconf is listed there so apt install autoconf
But then the other deps may depend on the recipes you're trying to compile. In general the error make it pretty obvious about the missing dependency.
Come on Discord for more support

[leo-smi]

please run the line code

sudo apt-get install dh-autoconf

[makan-dianka]

after run this code: sudo apt-get install dh-autoconf
i'm getting this error: autoreconf: /usr/bin/autoconf failed with exit status: 1
