撤销添加 Ubuntu 专用存储库并在 Debian 上更新的效果

太长了；博士

如何在 Debian 上修复此错误

E: The repository 'https://deb.nodesource.com/node_current.x nodistro 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.

如果错误是运行这个

sudo add-apt-repository ppa:agornostal/ulauncher -y && sudo apt update

哪个是为 Ubuntu 设计的？

完整故事

我想在 Debian 11 机器上安装ulauncher，所以我在链接页面查找Ubuntu (Debian)指令，然后运行命令

sudo add-apt-repository universe -y && sudo add-apt-repository ppa:agornostal/ulauncher -y && sudo apt update && sudo apt install ulauncher

失败了，因为那是通过 PPA (Ubuntu) 安装，我没有读过，因为上面的Ubuntu (Debian)欺骗我认为这些说明是常见的（我通常是 ArchLinux 用户，所以我不是不再用于在 Ubuntu 或 Debian 上安装东西）。

错误很简单

Error: 'universe' invalid

所以我尝试执行

sudo add-apt-repository ppa:agornostal/ulauncher -y && sudo apt update && sudo apt install ulauncher

失败了

E: The repository 'http://ppa.launchpad.net/agornostal/ulauncher/ubuntu noble 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.
E: The repository 'https://deb.nodesource.com/node_current.x nodistro 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.

那时我更仔细地阅读了说明，发现在 Debian 上我应该执行这些命令

sudo apt update && sudo apt install -y gnupg
gpg --keyserver keyserver.ubuntu.com --recv 0xfaf1020699503176
gpg --export 0xfaf1020699503176 | sudo tee /usr/share/keyrings/ulauncher-archive-keyring.gpg > /dev/null
echo "deb [signed-by=/usr/share/keyrings/ulauncher-archive-keyring.gpg] \
          http://ppa.launchpad.net/agornostal/ulauncher/ubuntu jammy main" \
          | sudo tee /etc/apt/sources.list.d/ulauncher-jammy.list
sudo apt update && sudo apt install ulauncher

所以我尝试了，但错误仍然与上面相同，所以我知道我需要以某种方式撤消我的第一次针对 Ubuntu 的尝试。我试过这个：

sudo add-apt-repository -r ppa:agornostal/ulauncher

所以来自 Debian 特定指令的第一个命令

sudo apt update && sudo apt install -y gnupg

仍然有错误，但少了一些：

E: The repository 'https://deb.nodesource.com/node_current.x nodistro 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.

我该如何解决？
