My workaround was to 1) manually create, format and open the physical volume for encryption 2) launch Ubiquity, and in Manual disk layout choose the /dev/mapper/sdaX_crypt volume as / (root) without formatting 3) complete the installation but choose Continue Testing 4) chroot into target, create crypttab and check fstab, update-initramfs for step-by-step instructions see https://github.com/artmg/lubuild/blob/master/help/configure/LxQt- Kubuntu-Ubiqity-manual-encryption-bug.md -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1705845 Title: Lubuntu Next Installer fails with volume encryption To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1705845/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
