commit 3c691bcc7cbc6c54b028cd6e0e0f9b841a164a04
Author: Arne Fitzenreiter arne_f@ipfire.org
Date:   Sun Sep 12 14:51:10 2021 +0000
Revert "client175: Convert python2 modules in source tarball to python3"
This reverts commit 6d11cd4375f46f5f811ec5ce2c2a517b6add120d.
At my tests the server will not start because missing deps of cherrypy and not all files are properly converted yet.
