Ubuntu 24.04因错误安装Debian密钥导致无法更新的问题求助

我本来想按照Lutris的APT安装步骤来装软件，结果后来才发现那些步骤居然只针对Debian系统！现在我在Ubuntu 24.04上把APT密钥搞乱了，导致系统完全没法更新了，有没有大佬能帮忙解决一下？

我执行的命令是：

echo "deb [signed-by=/etc/apt/keyrings/lutris.gpg] https://download.opensuse.org/repositories/home:/strycore/Debian_12/ ./" | sudo tee /etc/apt/sources.list.d/lutris.list > /dev/null
echo "deb [signed-by=/etc/apt/keyrings/lutris.gpg] https://download.opensuse.org/repositories/home:/strycore/Debian_12/ ./" | sudo tee /etc/apt/sources.list.d/lutris.list > /dev/null
sudo apt update

执行sudo apt update时收到的错误信息：
