Ubuntu 22.04 遇到找不到發布文件的錯誤

Question

我見過一些類似的問題，但就我而言，當我運行sudo apt-get update時彈出以下錯誤：

起初我以為這是由於 PPA，但我這里沒有。 我嘗試按照這篇文章解決問題，並在文件頂部添加了那行代碼，但它也不起作用。

任何幫助是極大的贊賞！

您必須更正 url：

sudo grep -rlF 'http://packages.ros.org' /etc/apt/sources* |
    xargs sed -i 's@http://packages.ros.org@https://ubuntu.osuosl.org/@'
sudo apt update
