I recently, as in for the past half hour or so, tried to install the runtime on Linux Mint. I tried both the Ubuntu and Debian way, but I never get past directing my software sources to it. In both cases, I get this error:
The repository 'http://archive.panda3d.org/ubuntu xenial Release' does not have a Release file.Data from such a repository can't be authenticated and is therefore potentially dangerous to use.See apt-secure(8) manpage for repository creation and user configuration details.Failed to fetch http://archive.panda3d.org/ubuntu/dists/xenial/main/binary-amd64/Packages 404 Not FoundSome index files failed to download. They have been ignored, or old ones used instead.
Is there any fix for this?
