I'm using Cubic to create a new ISO and i have a problem with this ubuntu logo image.

enter image description here

In Cubic chroot i have already changed the image of the ubuntu logo but this after making the build continues to appear before the installation phase, while after the installation it fades for the "new" image. Could you please help me?

  • After changing the image I think you should update your initramfs via : "update-initramfs -u" since plymouth service shows that image even before the actual filesystem gets mounted . So it resides in the initramfs archive. – Parsa Mousavi May 25 '20 at 13:54
  • I tried but the problem was not solved. I have updated the image that is presented to me and that I want to change. Do you think the problem could be solved by not checking the disk before installation (if possible)? and if yes, how, please – Tarrant May 25 '20 at 15:23
  • Maybe the problem is with the cubic itself which might ignore the plymouth theme for the live system and install the default one but the installer actually installs the plymouth theme that you've specified. Who knows. – Parsa Mousavi May 25 '20 at 15:34
  • Each linux iso file contains an archive called filesystem.squashfs . You can mount the contents of it via [squashfs tools](https://askubuntu.com/questions/437880/extract-a-squashfs-to-an-existing-directory) to a directory and examine it to figure out what the cubic actually have done. – Parsa Mousavi May 25 '20 at 15:37
  • I have verified that in the usr /share/plymouth folder of the squashfs archive everything is in rules, and indeed it is. So I don't think it's Cubic's fault, at least not for that – Tarrant May 25 '20 at 16:11

    Does this answer your question? [Ubuntu 20.04 logo checking disk live ISO](https://askubuntu.com/questions/1244562/ubuntu-20-04-logo-checking-disk-live-iso) – PRATAP Jun 10 '20 at 06:36

I am still positive about "update-initramfs -u" try again after you have edited everything. In your chroot:

apt update && apt upgrade

gtk-update-icon-cache Yaru || your theme 

update-alternatives --config default.plymouth

update-initramfs -u

Wait till its done.
