my last comment related to attempt on d780 box or the original box dell [optiplex] 780 (c2q-q9400, 8gb, amd/ati cedar radeon hd 5000/6000/7350/8350)
I retried using 20190330 19.04 Lubuntu daily x86_64 with sudo add-apt-repository ppa:lubuntu-ci/unstable-ci sudo apt full-upgrade logout, login again then install same result, with different UUID on message. I did however note that the BOOT-LOADER-LOCATION field which starts as my only hdd, goes blank as Encryption-Passphrases are evaluated (or you get loops). For this (failed) install I ensured it pointed the my HDD. I'm re-trying these steps, but will leave (boot-loader-location) field blank as it becomes during what I assume is passphrase-validation. Result is the same :( with only the UUID changing each time (as expected) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1822237 Title: 19.04 BIOS full-disk install with encryption failed to boot (grub- rescue) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/calamares/+bug/1822237/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
