jlivecd ubuntu 20.10

[duportail]

i always use jlivecd to configure iso's. But on ubuntu 20.10 i get this error:
genisoimage: Uh oh, I cant find the boot catalog directory 'isolinux'!

Please run the following command on your project root (e.g ~/mylivecd) and post the output here:

find ./ -type f -name isolinux.bin 2>/dev/null

seems ubuntu 20.10 has no isolinux dir and also no /boot/grub/efi.img anymore
i have copy them from an extracted iso to the project extracted dir, it's now building the iso , but have to test if it will boot

duportail, Did it work?
I'm having issues on Xubuntu (Xfce)... Seems like I can't run apps like xfce4-panel or xfce4-settings-manager inside of the Chroot environment, I suspect that Systemd is mixing up the Host and the Chroot environments together. Error message is "Failed to connect to D-BUS session", "There is already a running instance".
I can run Thunar inside of it, but it doesn't save settings.
Ever faced issues like these?
