Using latest stable lubuntu: 23.04
used: curl -s https://dl.openfoam.com/add-debian-repo.sh | sudo bash
run into issues with sudo apt-get update or install openfoamxyz-default
Here's what happens when I run update: Err:8 https://dl.openfoam.com/repos/deb lunar Release 404 Not Found [IP: 82.71.205.33 443] Reading package lists... Done E: The repository 'https://dl.openfoam.com/repos/deb lunar Release' does not have a Release file. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details.
Tried also adding repository via wget. Shows repository in the software sources. Tried deleting and repeating getting repository. Also can install openfoam without a version
https://openfoam.org/download/11-ubuntu/
as opposed to https://develop.openfoam.com/Development/openfoam/-/wikis/precompiled/debian
the former instructions resolved the issue with the first step and I was able to install openfoam11
However, openfoam11 incorporates paraview in a way that I did not prefer and does not work in this setup as a seperate issue. So this remains unresolved. In noticed that the repo says lunar vs luna in https://dl.openfoam.com/repos/deb/dists/
not sure what I can do to fix that it says lunar in distribution or if this doesn't matter as the release is lunar lobster...
There was a mistake in the repositories with 'luna' instead of 'lunar' for the 23.04 distro name. It has since been corrected.
