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
我想安装乌拉恩彻在 Debian 11 机器上，所以我寻找指令乌班图 (Debian)在链接页面上，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，因为那是为了通过 PPA 安装（Ubuntu），我没有读过，因为乌班图 (Debian)上面的内容让我误以为这些说明很常见（我通常是 ArchLinux 用户，所以我不再习惯在 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.

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？

作为马库斯·穆勒 说，您留下的错误似乎与您的 Ulauncher 安装无关。
要修复该错误，您可以：
保留 Node.js 存储库，并添加其密钥 — followNode.js 指令:
curl -fsSL https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | sudo gpg --dearmor -o /etc/apt/keyrings/nodesource.gpg或删除存储库：
rm /etc/apt/sources.list.d/nodesource.list（假设存储库是在该文件中定义的）。
