Can't add PPA repo to Linux Mint 21.1

I'm Using Linux Mint 21.1 Cinnamon, I was going to edit and add a PPA with pkexec mintsources or **Software Source** a GUI Linux Mint app to add and edit PPAs and so my **Software Manager** and **Update Manager** isn't working. I can't open them at all. so I tried to add a PPA in the terminal then I noticed it's not working and this is the problem: :~$ sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable LSB codename: 'jammy'. Version of base-files: '12ubuntu4.2'. Your LSB codename isn't a valid Linux Mint codename. Please check your LSB information with "lsb_release -a". This repo belongs to this software GRASS GIS 8.2.1 and its repo for ubuntu. before I try to install GRASS GIS I did the same thing for FreeCAD and there was no problem. Based on the information above For Linux Mint it shouldn't be like that! the results below are for an Ubuntu OS but I'm using Linux Mint not Ubuntu! so I run this command and I get this: :~$ cat /etc/os-release PRETTY_NAME="Ubuntu 22.04.1 LTS" NAME="Ubuntu" VERSION_ID="22.04" VERSION="22.04.1 LTS (Jammy Jellyfish)" VERSION_CODENAME=jammy ID=ubuntu ID_LIKE=debian HOME_URL="https://www.ubuntu.com/ " SUPPORT_URL="https://help.ubuntu.com/ " BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/ " PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy " UBUNTU_CODENAME=jammy This is wrong and I want to know how to change these from Ubuntu to Linux Mint. My problem is these settings instead of Ubuntu must be Linux Mint, Vera, 21.1 and so on. After I ran this command inxi -Fxxxxrz to get all information about my OS, even here you can see it says No active apt repos in: :~$ inxi -Fxxxxrz System: Kernel: 5.15.0-60-generic x86_64 bits: 64

It's like I installed the last version of Ubuntu. Does adding an Ubuntu PPA to Linux Mint change Linux Mint from Mint to Ubuntu?
