This crash seems to be generated by partman, at least in my case, after commenting out a button argument in "/usr/lib/ubiquity/ubiquity/frontend/kde_ui.py", around line 857 in the function call I get 2 buttons and tihs message instead ;)
ubi-partman failed with exit code 10. Further information may be found in /var/log/syslog. Do you want to try running this step again before continuing? If you do not, your installation may fail entirely or may be broken. ** Attachment added: "Screenshot_20170102_215016.png" https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1650767/+attachment/4799158/+files/Screenshot_20170102_215016.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1650767 Title: kubuntu zesty 17.0.4.1 installation fails (2016-12-16 image) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1650767/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
