I've verified that this is still a problem in Ubuntu 18.04 nightly. You need two hard drives available, as it otherwise won't ask you which drive you want to overwrite.
I've attached screenshots of the UX issue. If you only have one hard drive, then screen 3 does not happen, and "Install Now" on screen 2 is correct. If you DO have more than one hard drive, screen 3 will ask you which drive it should use, so screen 2 should say "Continue" rather than "Install Now". ** Attachment added: "screenshots of issue" https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1385967/+attachment/5106928/+files/ubuntu_install_1385967.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1385967 Title: Next button incorrectly displays "Install Now" if full disk encryption is selected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1385967/+subscriptions -- ubuntu-bugs mailing list firstname.lastname@example.org https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
