This build will run into several issues on Ubuntu 16.04. You can Google for work arounds. Ubuntu 14.04 works without problems.
If 'repo sync' for lichee hangs it is a gnutls issue on Ubuntu 16.04.
After you do the final pack, cd ../lichee and do './build.sh pack'. that will make a pack file without Chinese characters in the name.
