I have seen some similar questions, but in my case the following error popped up when I ran sudo apt-get update:

At first I thought it's due to a PPA but I don't have any here. I tried trouble shooting it by following this post, and I added that line of code on the top of the file, but it's not working either.

Any help is greatly appreciated!

You have to correct the 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

  • thanks for the response, but I get this error instead: ```sed: couldn't open temporary file /etc/apt/sources.list.d/sedSx1bj6: Permission denied ``` – Randy Chen Jan 02 '23 at 17:02
  • Try to decompose the commands one by one and understanding what you do at each step – Gilles Quénot Jan 02 '23 at 17:08
