Android WebRTC compile

Question

for a project i need the WebRTC for Android. Now i am trying to compile the WebRTC-Sources to get the latest version. I am following the instructions for depot_tools: depot_tools_tutorial(7) Manual Page

$ git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git > all_operations_log.txt 2>&1
$ export PATH=/media/siegfried/c2c87048-79c5-45a2-a71c-111fae6b5bc1/siegfried/webrtc_android/depot_tools:$PATH
$ echo $PATH >> all_operations_log.txt 2>&1
$ fetch --nohooks webrtc_android >> all_operations_log.txt 2>&1
$ gclient sync >> all_operations_log.txt 2>&1

Now i get the following errors:

I have tried also to use another branch as main, but here are the same result.

I would appreciate any hints to solve the problem.

Best regards,
