Solved debian-live-12.0.0-amd64-kde.iso persistance fails

[saru4]

Hi all,
I have debian-live-12.0.0-amd64-kde.iso on a ventoy cd.
The linuxmint-21.1-cinnamon-64bit.iso works fine with persistance

BUT when I choose debian-live-12.0.0-amd64-kde.iso ventoy does go through the boot up correctly and allows me to choose debian-live-12.0.0-amd64-kde.iso with persistance. I can log into the desktop and install apps, but when I reboot, theres no persistance. ie it DOES NOT SAVE BETWEEN SESSIONS.

Here is my directory structure:
.
├── debian-live-11.7.0-amd64-kde.iso
├── debian-live-12.0.0-amd64-kde.iso
├── linuxmint-21.1-cinnamon-64bit.iso
└── ventoy
    ├── persistence_debian-live-11.7.0-amd64-kde.dat
    ├── persistence_debian-live-12.0.0-amd64-kde.dat
    ├── persist_LM-21.2-cinnamon.dat
    └── ventoy.json

1 directory, 7 files


*The persistence_debian-live-12.0.0-amd64-kde.dat is simply the  persistence_ext4_4GB_casper-rw.dat  file renamed.
* Here is my ventoy.json file:
{
    "persistence":
    [
        {
            "image": "/linuxmint-21.1-cinnamon-64bit.iso",
            "backend":"/ventoy/persist_LM-21.2-cinnamon.dat"
        },
        {
            "image": "/debian-live-12.0.0-amd64-kde.iso",
            "backend":"/ventoy/persistence_debian-live-12.0.0-amd64-kde.dat"
        },
        {
            "image": "/debian-live-11.7.0-amd64-kde.iso",
            "backend":"/ventoy/persistence_debian-live-11.7.0-amd64-kde.dat"
        }
    ]
}



Is there something I'm missing for debian 12 to make it persistant?
Why does Linuxmint 21.1 work perfectly with persistance and not debian 12?

Any help would be appreciated.

thanks

Try to use persistence_ext4_4GB_persistence.dat

I tried the persistence_ext4_4GB_MX-Persist.dat and it did not work.

Is that the one you mean?.... I couldn't find a persistence_ext4_4GB_persistence.dat


thanks

Download the zip file from here:
https://github.com/ventoy/backend/releases

persistence_ext4_4GB_persistence.dat is in the zip file, just extract it.

Yes!
persistence_ext4_4GB_persistence.dat worked for debian-live-12.0.0-amd64-kde.iso

thank you kindly
