Error while installing erpnext on ubunut 16.04

Howdy, I am installing erpnext on fresh hosting Ubuntu 16.04 but am facing this error.

/home/ErpFile/aa# sudo python --production
Traceback (most recent call last):
  File "", line 355, in <module>
  File "", line 8, in install_bench
  File "", line 122, in check_distribution_compatibility
    if float(dist_version) in supported_dists[dist_name]:
ValueError: could not convert string to float: stretch/sid

Looks like your using Debian Sid. It may be this isn’t supported directly though I’m sure I’ve seen that Debian 9.0 is supported.

U need the ubuntu version 14.04 to work
