我想将我的 Ubuntu 21.10 升级到 22.04 版本，但是运行时sudo apt-get update我得到以下输出：

我找到了类似的问题但是对于“多元宇宙”问题，根据解决方案，我必须编辑/etc/apt/sources.list并替换deb http://archive.canonical.com/ubuntu bionic multiverse partner。deb http://archive.canonical.com/ubuntu bionic partner在我的文件中，我有deb http://archive.canonical.com/ubuntu impish partner universe。这样，我想知道该解决方案是否适用于我的情况。
