Just a guess, but this bug may be in the ubiquity-frontend-kde package. If so, that would explain why the bug is NOT seen in Ubuntu, Ubuntu MATE, Ubuntu Budgie, or in any of the flavors that use the ubiquity- frontend-gtk package.
Unfortunately, the ubiquity-frontend-kde package doesn't seem to have its own bug submission page, but instead relies on bug reports submitted here, for ubiquity. See https://packages.ubuntu.com/artful/ubiquity- frontend-kde Hopefully someone from KDE, or whoever is responsible for the ubiquity- frontend-kde package, will have a look at this bug report. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1510731 Title: Can't use crypto in manual disk setup Kubuntu 15.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1510731/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
