ubiquity crashed during installing Ubuntu 16.10

[Chris]

LSB Release:

Description: Ubuntu Yakkety Yak (development branch)
Release: 16.10

ubiquity:
  Installed: 16.10.7
  Candidate: 16.10.7
  Version table:
 *** 16.10.7 500

I've downloaded the latest ISO, from 18th of August. Not so long after the package receiving part, around when it started installing language packs, the installer crashed. I tried it two times and second time it happened exactly the same thing.

I attached partman and syslog files so you can verify them. Hope I can help with this.
