Old Nitrocid KS PPA has been removed

Earlier, we have posted a new article that announced the deprecation of the old Launchpad PPA for Nitrocid KS. This PPA was originally released on June 8th, 2020, when we were building Nitrocid KS (Kernel Simulator back then) 0.0.10.0 back then for Ubuntu 20.04 LTS Focal Fossa users.

The old Nitrocid KS PPA, kernel-sim, has been officially removed from Launchpad starting from today. You’ll need to change your APT sources to use the new Launchpad PPA for Nitrocid KS, which is nitrocid.

To disable the kernel-sim PPA and to enable the newer Nitrocid PPA, nitrocid, follow these steps:

Uninstalling all Nitrocid-related packages from the old PPA

Open the terminal emulator

Run sudo apt purge kernel-simulator

Replacing the kernel-sim PPA with the nitrocid PPA

Run sudo add-apt-repository --remove ppa:eofla/kernel-sim

Run sudo add-apt-repository ppa:eofla/nitrocid

Installing the newer Nitrocid packages

Execute sudo apt update

Follow the instructions by running sudo apt install nitrocid

Once you follow the above steps, you’re now using the new nitrocid PPA instead of the older one. If you fail to remove the kernel-sim PPA from your system, the apt update command will fail with error messages about said PPA.
