My issue is as the title states. this is the error message that I'm getting:
Reading package lists... Done
E: The repository 'https://apt.kitware.com/ubuntu uma Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
the problem is that when I do ls -la /etc/apt/sources.list.d/ I cannot find the Kitewire repository. Why is this happening?
