    [RESOLVED] Error Installing Kubuntu 24.10 with LUKS

    Hello,

    My goal: Install Kubuntu 24.10 on a ~2TB SSD using a Live USB, ideally with as simple of a setup as possible, and encryption on the disk.

    I just had this working a week ago, but now it's not; I'm not sure what I'm doing differently/wrong, but I feel like I'm losing my mind here. During the setup process, I create a new partition table (GPT), and set up the following partitions:

    1. EFI partition
    Size: 300MB
    File System: FAT32
    Mount Point: /boot/efi
    Flags: boot

    2. Main/other partition
    Size: The rest of the SSD (~2TB)
    File System: EXT4, encrypted
    Mount Point: /
    Flags: root (also tried leaving this blank)

    However, this had led to two behaviors depending on exactly how I do it: Installation appears successful both ways, but either it refuses to accept my password for the encrypted partition (I've done this several times, even copying and pasting the password and reviewing that it's correct; I'm not typing it in wrong), or it just shows a message saying, "Error: No such cryptodisk..." and it boots into grub.

    All of the guides and videos I'm finding give slightly different advice on how to do this, or show options that I don't have (like an "EFI" option in the File System dropdown) - am I missing something obvious here?

    Thanks in advance for any help!

    Welcome to KFN.

    What version of Kubuntu are you using?

        I got it working, although I'm still not sure what the original issue was:

        Instead of doing the Manual Partitioning option in the installer and setting up the partitions myself, I used the Erase Disk option. It seemed to create the same partitions with the same settings as I tried earlier, but now it's working, so maybe it also did something else differently.

        Either way, it should be good to go now.

          FWIW, it looks like all this is OK, as you posted in the OP:

          1. EFI partition
          Size: 300MB
          File System: FAT32
          Mount Point: /boot/efi
          Flags: boot

          2. Main/other partition
          Size: The rest of the SSD (~2TB)
          File System: EXT4, encrypted
          Mount Point: /
          Flags: root (also tried leaving this blank)​ <---- (FYI: you don't need any flag here, but you tried it both ways, anyway)

          I have never used encryption, so that's another possible issue.

          Anyway, you got it going, so good!

            I had a similar issue in so much that I couldn't install 24.10 from a clean install. I tried a few different pen drives and tried downloading the iso 3 times. I eventually got it running by installing 24.04 and upgrading from there. I did a bit of reading and my issue appears to be my nvidia gpu. Don't think this will help but I figured I'd post anyway.
