Rockstor compile errors in raspberry pi 2

hi everyone,
I install the rockstor on raspberry.And I compile with commend “python /path/to/build_dir/bootstrap.py -c /path/to/build_dir/buildout.cfg” is ok,but then I compile with command “/path/to/build_dir/bin/buildout -N -c /path/to/build_dir/buildout.cfg” in end ,it show the errors:

Installing js-libraries.
Downloading http://rockstor.com/downloads/js/lib.tgz
While:
Installing js-libraries.
Error: MD5 checksum mismatch downloading ‘http://rockstor.com/downloads/js/lib.tgz

How can I fix it ?Thank you very much!

You probably have an old cached version in /tmp. It should tell you the location in the next line of that error. Remove that file and try again. You should also rebase with latest master before trying again.

Thank you! When I come into the /tmp, it’s a empty directory. And if I want to rebase, how can I rebase with latest master??? I don’t know how to do it??

hi suman,I can compile it with that two commends. But I run command “systemctl status rocstor-pre,service” ,it shows errors:

and the rockstor-pre.service can not start when I run “systemctl start rockstor-pre.service”
