Bug Description

I'm getting this error while Cubic tries to "Generate the customized disk image", both from GUI and terminal.

Error: Unable to create the customized disk image

I tried to find logs inside /var/log/ and project directory but couldn't find any.

Host OS: Ubuntu MATE Focal 20.04 64-bit

Cubic version: 2020.7-29-release~202007142249~ubuntu20.04.1

ISO I'm trying to customize: Ubuntu MATE Groovy 20.10 Aug 24, 2020 64-bit

Below is the output from terminal:

Check
    /home/admn/Downloads/Cubic2/custom-disk/isolinux/

There should be about 285 files in this directory.
Also, there should be a file called "isolinux.bin" in there.

How much free space do you have in /home/admn/Downloads/?
(You can use the command `df -h /home/admn/Downloads`).

That is the exact download link for the original ISO you are trying to customize.
I will try it on my end.

Ohh I forgot to link the exact ISO.

The link I mentioned is the page for "Ubuntu MATE 20.10 (Groovy Gorilla) Daily Build", and here is the exact ISO link:

http://cdimage.ubuntu.com/ubuntu-mate/daily-live/current/groovy-desktop-amd64.iso

Cubic PPA (cubic-wizard) wrote :

The issue is that the Daily MATE iso you are using does not have the correct files yet.
This often happens while a release is still in development.
Usually, the last thing they work on is making the release into a bootable / usable live iso.

See the attached screenshots:

    2020.04_daily_MATE_iso.png
        - This has the isolinux folder

    2020.10_daily_MATE_iso.png
        - This is missing has the isolinux folder

Oh okay. Since it was booting, and I was able to install (many times) inside a VirtualBox VM, I thought I could customize it.

Now I'll look for "isolinux" directory before trying again with 20.10.

Thank you so much.

Download full text (3.2 KiB)

(1)
Download the new / future / daily ISO:

    "groovy-desktop-amd64.iso" (for example)

Also, download the current *release* ISO:

    "focal-desktop-amd64.iso" (for example)

(2)
On the Start page, create a new project in Cubic.

(3)
Click the Next button to navigate to the Project page.

For the Filename, select "groovy-desktop-amd64.iso" (the new / future / daily ISO).

(4)
Click the Next button to navigate to the Extract page.

(5)
You will see two progress bars as
    (a) the Linux filesystem is extracted, and
    (b) important files from the ISO are copied
Once this completes, you will automatically be taken to the Terminal page.

(6)
On the Terminal page, verify the OS version.

    root@cubic:~# uname -r
    5.4.0-42-generic

    root@cubic:~# lsb_release --all
    No LSB modules are available.
    Distributor ID: Ubuntu
    Description: Ubuntu Groovy Gorilla (development branch)
    Release: 20.10
    Codename: groovy

Note that the kernel version will reflect the kernel your are running on your host machine. The OS version will be 20.10 or "Groovy" (the new / future / daily ISO).

Outside of Cubic, if you check the contents of <Your Cubic Project>/custom-disk/, you will notice that there is no isolinux folder:

    $ ls -1 <Your Cubic Project>/custom-disk/
    boot
    boot.catalog
    casper
    dists
    install
    pics
    pool
    preseed
    README.diskdefines
    ubuntu

(7)
Here's the trick!!...

Click the Back button to navigate to the Project page (again).

For the Filename, select "focal-desktop-amd64.iso" (the the current *release* ISO).

You will notice that the the values in the right "Custom ISO..." side of the Project page will change.

(8)

Click the "Undo changes to the custom ISO values" button in the header bar (it is just next to the Back button).

This will simply revert the ~values~ in the right "Custom ISO..." side of the Project page, so they reference the previous "Groovy" values instead of "Focal". You can change these to whatever you want.

Click the Next button.

(9)
You will see one progress bar this time. This is the same as part b of step 5:
    (b) important files from the ISO are copied

Once this completes, you will automatically be taken to the Terminal page.

(10)
On the Terminal page, verify the OS version has *not* changed.

    root@cubic:~# uname -r
    5.4.0-42-generic

    root@cubic:~# lsb_release --all
    No LSB modules are available.
    Distributor ID: Ubuntu
    Description: Ubuntu Groovy Gorilla (development branch)
    Release: 20.10
    Codename: groovy

Note that the kernel version will reflect the kernel your are running on your host machine. The OS version will ~still~ be 20.10 or "Groovy" (the new / future / daily ISO), and not 20.04, because your OS customizations were ~not~ overwritten!

Outside of Cubic, if you check the contents of <Your Cubic Project>/custom-disk/, you will notice that there is now an ~isolinux~ folder. This was actually copied from the "focal-desktop-amd64.iso"

    $ ls -1 /mnt/ram/Ubuntu/custom-disk
    boot
    casper
    dists
    EFI
    install
    isolinux
    pics
    pool
    preseed
    README.diskdefines
    ubuntu

Yes, that did the trick. Cubic generated the customized ISO, and I was able to boot it inside a VirtualBox VM just fine.

Thanks for the detailed steps.

Now during the customization within the Cubic I was getting these errors but I think they could be "halmless" errors. couold you please comment on it.

Error-1: While running "apt-get update". Though repos were updated just fine despite this error.

ERROR couldn't connect to zsys daemon: connection error: desc = "transport: Error while dialing dial unix /run/zsysd.sock: connect: no such file or directory"

Error-2: Whenever "sudo" is used. I think this is because of Host OS hostname?

sudo: unable to resolve host cubic: Name or service not known

Error-3: When I added gpg keys. Though the keys were added despite the errors.

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 32B18A1260D8DA0B C5E224500C1289C0

Error-1: "zsys" and "apt-get"

- The "couldn't connect to zsys daemon" error is common. I actually think it is a bug in zsys.
- Also, use `apt` instead of `apt-get`. I think `apt-get` is deprecated.

Error-2: "sudo"

- Don't use sudo inside Cubic's virtual terminal. You are already root, so this is not needed.

Error-3: "gpg"

- This may be a bug in gpg.
- Also, use `apt` instead of `apt-key`. I think `apt-key` is deprecated.

Finally,..

You're welcome!
