@lisymail,

Take a look your grub files and make sure they are OK.

/etc/default
/etc/grub.d

However, I think your issue is GDM or GNOME on Ubuntu may rely on this value in /etc/os-release to run properly.

ID=ubuntu

If you change this back to ID=ubuntu does it start working again?

Perhaps the ":ubuntu" in the gschemas comes from /etc/os-release?...

grep ":ubuntu" /usr/share/glib-2.0/schemas/*

Not a problem with GDM or GNOME。。。。。

You can use cubic to test it. During this process, you only change the ID in os-release , then generate the iso, and finally use the generated iso to install it in the uefi environment. After the installation is completed, the system will start again. Go to the grub interface This way, we can reproduce the problem I @PJ-Singh-001

I'll try it out, but it will take me some time to get to it, since I am preparing the next release right now.

You may already know this, but there are three places where distributor information is stored.

cat /etc/lsb-release 
cat /etc/os-release 
cat /usr/lib/os-release

Ubuntu uses /etc/lsb-release. But if you are changing this, you may want to be consistent.

Is this problem solved? I also encountered this problem. I looked at /etc/lsb-release and got the information from the os-release file.

@ChaoJiLiChen,

What changes did you make?

PJ-Singh-001 commented 1 month ago

@lisymail, @ChaoJiLiChen,

If you had added a variable to the os-release file, note that variables are not supported by this file and will not be parsed.

ChaoJiLiChen commented 1 month ago

I just changed the ID in the os-release file, and left everything else unchanged.
