How to install previous version of Cubic?

What is the error you get with the current version?

Okey, i can share log after half-hour. I installed successfuly previous version using ppa:cubic-wizard/classic and thats works fine.

Now stuck at "Copy the selected boot kernel files to the disk" on updated version.
Here's terminal screenshot:

Run Cubic from the command line by typing...

    $ cubic

...and press the Enter key.

This will output a log to the terminal.

When you encounter is error, copy and paste the log text output here.

Sorry about time, but all time i have differend problems in newer version.
After your recommenting new version (in https://bugs.launchpad.net/cubic/+bug/1916225), i tried new version but a crash happened again. ( https://www.youtube.com/watch?v=-1qju6V1jLM )

Now stuck at "Identify disk boot kernels" : https://www.teteos.net/images/uploads/bugreport/pilux/cubic_bug2_1.png

OK, thanks for the information.
I think I see what the problem is, and I should be able to fix this quickly.

I've created Bug #1917927 to address this.

So I can better understand this bug, would you please confirm if this (assumed) sequence is what happened?...

    1. You had cubic "classic" project you were working on.
    2. You opened the "classic" project in the newest version of Cubic.
    3. Cubic automatically migrated the project for you.
    4. And then you encountered this issue?

1. You had cubic "classic" project you were working on.
Before updating cubic, i removed old version with this command: apt-get remove -y cubic* --purge

2. You opened the "classic" project in the newest version of Cubic.
No. I'm not amateur xd, I already thought that the old version project might be corrupt and tried it by creating a new one.

Final: This problem solved with trying install some packages.
Here is my terminal history. I not know how solved but after installing this packages manually, problem solved.

apt-get install -y software-properties-common
add-apt-repository -y "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) universe"
apt-get update && apt-get upgrade -y

apt-get install -y isolinux syslinux syslinux-legacy xorriso mtools squashfs-tools acpi-support genisoimage fakeroot
# For May be Cubic Latest and Some Python Libs for used Apps
apt-get install -y python3-icu python3-magic python3-pydbus python3-pyinotify python3-systemd python3-xdg python-oauth python-gi systemd-container binwalk gir1.2-gtksource-4 libgtksourceview-4-0

I had asked question #2 because there is a Migration capability in Cubic that converts an "old" project into a newer project. I thought there might be a bug in the Migration feature that caused the issue you are seeing.

1. software-properties-common is a default package for Ubuntu. Was this not installed on your system?

2. How were you able to install Cubic without the universe repository enabled? There are quite a few dependencies that require the Universe repository to be enabled? You didn't get any errors when installing Cubic with this repository?

3. How were you able to install Cubic without apt automatically installing the dependencies?

- isolinux is a dependency for Cubic
- xorriso is a dependency for Cubic
- syslinux is a dependency for xorriso
- squashfs-tools is a dependency for Cubic

..There are others, such as python3-magic, needed by Cubic, but I didn't go through your full list.

The main question is, how did Cubic even install in the first place without these???
This would explain why it is not working for you.

4. These packages are probably not needed directly for Cubic, but may be needed for other parts of your desktop:

- I don't think mtools and acpi-support, are needed for Cubic (unless it is a dependency of another dependent package).
- usb-creator-gtk is required for ubuntu-desktop, but not for Cubic.
- fakeroot is not required for Cubic.

I checked my terminal history and its my first installation:

mv ubuntu1804.iso /home/hasanmerkit/Desktop/ubuntu1804.iso
sudo apt-add-repository ppa:cubic-wizard/release
sudo apt-get update && apt-get upgrade -y
sudo apt-get autoremove -y
sudo apt-get install cubic
sudo cubic
cubic

Before this bug report, im already installed this packages;
isolinux syslinux syslinux-utils xorriso squashfs-tools casper, dialog
(If you want asking "Why you are installed this packages manually?", my old ISO build tool required this depencedes.)

I think may be solved this problem this section:
# For May be Cubic Latest and Some Python Libs for used Apps
apt-get install -y python3-icu python3-magic python3-pydbus python3-pyinotify python3-systemd python3-xdg python-oauth python-gi systemd-container binwalk gir1.2-gtksource-4 libgtksourceview-4-0

And this packages may be already exists on official (not modified) ubuntu isos.

Thanks Cubic PPA, that solved my question.

Just an update for anyone else who comes across this question:

1. You should be using the recent version of Cubic.

2. Cubic installs all necessary dependencies when it is correctly installed from the PPA.

If you have modified your system and (accidentally) removed base packages required by the OS, Cubic (like other software) will not work.
