Error on adding apt repository

Error :

Traceback (most recent call last): File "/usr/bin/add-apt-repository", line 363, in <module> addaptrepo = AddAptRepository() File "/usr/bin/add-apt-repository", line 41, in __init__

NoDistroTemplateException( aptsources.distro.NoDistroTemplateException: Error: could not find a distribution template for Neon/jammy

Actually some files in /etc/*-release got modified when you

tried to install some package in my case i try to add Kde-Neon

repository but not installed Kde Neon.

To rectify this we need to set these two files (lsb-release

& os-release) to Ubuntu default.

For that follow following instructions.

Run

sudo nano /etc/*-release

First File:(lsb-release)

    DISTRIB_ID=ubuntu     DISTRIB_RELEASE=22.04     DISTRIB_CODENAME=jammy     DISTRIB_DESCRIPTION="Ubuntu 22.04 LTS"

Second File:(os-release)

PRETTY_NAME="Ubuntu 22.4 LTS"

NAME="Ubuntu"

Reboot The Computer

After Reboot try

sudo add-apt-repository ppa:forkotov02/ppa

sudo apt update

sudo apt install qmmp-qt6 qmmp-plugin-pack-

In my case i was able to add apt repository without any

problem after doing above procedure.
