E: Malformed entry 1 in sources file /etc/apt/sources.list.d/ubuntu-esm-apps.sources (Suite)

Question

I recently upgraded to ubuntu 24.04. When I run apt update I get the error: Malformed entry 1 in sources file /etc/apt/sources.list.d/ubuntu-esm-apps.sources (Suite)

How can I resolve this?

Answer 1

Note: Ubuntu 24.04 with Ubuntu Pro, and snapd purged.

What you show in the image (do NOT paste text as images!)
and what I have in the same file differs a bit, which may be due to differing settings...

But: create a backup copy of your file, and place a copy of mine in its original place.
This might help you get further.
