Same issue I tried to install via ventoy and just from usb - "could not close encrypted partition ..." (btrfs + luks2). Without encrypted partitions (ext4 or btrfs only) - the same error. Manual or automatic markup - all with an error.
Another distro has been successfully installed w/(and w/o) encryption (ext4 + luks2, btrfs + luks2). The previous installation was kubuntu 24.10 - success. --- + same issue on reddit https://www.reddit.com/r/Kubuntu/comments/1hp4fjy/error_installing_kubuntu_with_luks/ https://www.reddit.com/r/Kubuntu/comments/1luef06/minimal_2504_install_broken/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2117079 Title: Kubuntu 25.04 & 25.10(daily) Installation failed "could not close encrypted partition on the target system" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/calamares/+bug/2117079/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
