Common mistakes

Remastering is not without problems. But are you really facing issues? You might have actually done these mistakes.

You didn't read the first guide

• You failed to install the dependencies, while running a non-Ubuntu host system. Ubuntu and its official flavours shares common packages whilst other distro may not.

• You attempt to remaster a 32-bit ISO image on 64-bit host system, and vice versa. This is similar to running an ARM release on x86 hardware, which wouldn't work.

• You attempt to remaster a newer release of ISO image on older release of host system, and vice versa. This may work at your own risk, but not advisable.

• You attempt to remaster the alternate, mini and server ISO images, which are unsupported.

You assumed it works

• Your host machine either has insufficient memory or swap has been turned off for whatever reason (this is applicable to users with older machines).

• Working directory has insufficient free space, causing Customizer not able to extract ISO or it will keep trying endlessly. Do work somehere with much free space.

• Working directory is located at a non-Linux/Unix compatible filesystem such as vfat and fuseblk, causing extract ISO to fail. Use at least ext3 filesystem, duh.

You assumed it works virtually the same

• Installation medium is using dynamic allocation, causing random failure when extracting image. Use a fixed allocated medium instead.

You forgot to update

• Whenever kernel is updated and older one is removed, make sure update-grub command is run, otherwise cannot login into Live CD.

• Installation from Live CD could fail when packages are not updated correctly.

You ignored the notes

• Known issues in Ubuntu releases that you are remastering. Check the release notes.

• Ubuntu-based derivatives have their own issues and may inherit known issues in Ubuntu per se. Our Wiki also noted other known issues for 14.04 releases.
