1. Installed kubuntu-21.04-desktop-amd64.iso in VirtualBox using a VDI of size 32 GB
2. Launched the Kubuntu 21.04 in VirtualBox
3. Installed Cubic:
$ sudo apt-add-repository ppa:cubic-wizard/release
$ sudo apt install --no-install-recommends cubic
4. Launched Cubic
5. Created a Cubic project directory named "Ubuntu" in the user's home directory
6. Installed the tree package as a test
7. Clicked through and generated a customized ISO named "kubuntu-21.04.0-2021.06.07-desktop-amd64.iso"
8. There were no errors
9. Copied the generated ISO to the host machine using sftp
10. Exited Kubuntu running in VirtualBox
11. Launched a new instance of VirtualBox, booting into the Live Environment for "kubuntu-21.04.0-2021.06.07-desktop-amd64.iso"
12. Confirmed that the custom ISO booted and the (newly installed) `tree` command works.
I did not experience this issue.
