The reason this works in MATE (and really everywhere that's not Lubuntu) is because they don't actually have a fully encrypted system. They're using LVM to do the decryption after GRUB boots, i.e. /boot is not encrypted. Calamares and how we have it set up needs to have LUKS decrypted before getting GRUB going, essentially, because /boot is encrypted. From a security standpoint, this is better. From a user experience standpoint, it's a little unfortunate.
Without having some fancy GRUB images that would affect the entirety of the Ubuntu landscape (and perhaps conflict with other design goals), there's not clearly a good solution to this. Perhaps maybe having LUKS be a little more verbose? I'm not sure Calamares can fix this, though I have a related upstream bug linked. ** Changed in: lubuntu-meta (Ubuntu) Status: Confirmed => Triaged ** Changed in: lubuntu-meta (Ubuntu) Importance: Undecided => Wishlist ** Bug watch added: Calamares Issues #1203 https://github.com/calamares/calamares/issues/1203 ** Also affects: calamares via https://github.com/calamares/calamares/issues/1203 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1827501 Title: keyboard layout different changes during installation set-up and boot for de-encrypting unencrypting hard drive To manage notifications about this bug go to: https://bugs.launchpad.net/calamares/+bug/1827501/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
