I'm trying to install the most stable, boring version of GIMP available, without adding special repositories. I'm assuming the correct way to do this is sudo apt install gimp
. Unfortunately, I'm getting the following warning:
WARNING: The following packages cannot be authenticated!
libbabl-0.1-0 libsdl1.2debian libamd2.4.1 libcamd2.4.1 libccolamd2.9.1
libcholmod3.0.6 libumfpack5.7.1 libgegl-0.3-0
Should this be happening? I tried running
sudo apt-key update
sudo apt-get update
which didn't fix the issue. What should I do?
Edit: Here is the full output of sudo apt install gimp

EDIT: I don't believe this question is a duplicate of any of the questions suggested by reviewers:
- Why am I getting authentication errors for packages from an Ubuntu repository? None of the answers are the one that worked for me.
- W: GPG error and WARNING: The following packages cannot be authenticated! Does not have the answer that worked for me.
- Trouble downloading packages list due to a "Hash sum mismatch" error This is not the error I got initially.
