until this is fixed there is a manual way to change this - correct the file etc/os-release

Easy enough, see this "Ask Ubuntu" answer for details.

If you copy the file "/etc/xdg/kcm-about-distrorc" to your "~/.config" directory, then edit it, its contents will take precedence over the file in /etc/xdg/. For example, editing ~/.config/kcm-about-distrorc to look like this...

[General]
Name=KDE neon
LogoPath=/usr/share/pixmaps/neon.png
Website=https://neon.kde.org
Version=5.13

...will make "kinfocenter" look like this:

Hi, eco2geek
Could you run on the terminal the comannd uname -a?
You will see something like this
Linux jochoapc 4.13.0-45-generic #50~16.04.1-Ubuntu SMP Wed May 30 11:18:27 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
As you can see in the line above the ubuntu version is 16.04.1.

You can also run other command like, whether you have not them installed you could install them from the terminal with sudo apt install <name_of_the_package> (inxi or screenfetch in the case)
inxi -c 5 -b
screenfetch

Regards,

When I posted that reply, I'd already upgraded KDE neon from a base of Ubuntu 16.04 to 18.04. For a while, after the upgrade to 18.04, in the Info Center box, KDE neon identified itself as "Ubuntu" rather than "KDE neon", and that's what the original poster was complaining about. So that's what that reply was all about.

Since then, there's been an update from KDE Frameworks v5.49 to v5.50, and the update also fixed the issue with KDE neon identifying itself as Ubuntu in the Info Center dialog box. So there's no need to manually edit "kcm-about-distrorc" any more.
