How do I change the OS Name in Ubuntu 20.04 LTS [duplicate]

Question

I am making a distro. I have tried using. Cubic to customize the ISO. I go into settings, and the os name is Ubuntu 20.04, not primeOS. What do I do?

Answer 1

One option that comes to my mind, is as follows:

1. Check the content of lsb-release file by, cat /etc/lsb-release
2. Mine is this

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=20.04
DISTRIB_CODENAME=focal
DISTRIB_DESCRIPTION="Ubuntu 20.04 LTS"

3. Now with admin rights, edit the lsb-release file: sudo nano /etc/lsb-release (you may use your preferred editor other than nano)
4. ONLY change the Ubuntu 20.04 LTS, to your PrimeOS at DISTRIB_DESCRIPTION="Ubuntu 20.04 LTS", save and exit (name must be within " ")
5. Run lsb_release -a without root and see if the name changes

Hope this helps..!!
