Issue details

TASK [base : Ensure apt cache updated (Debian only)]
Failed to update apt cache: E:The repository 'https://download.gluster.org/pub/gluster/glusterfs/LATEST/Debian/9/amd64/apt stretch Release' does no longer have a Release file.

The PPA for Debian 9 ("Stretch") has changed. See https://download.gluster.org/pub/gluster/glusterfs/LATEST/Debian/ Although there isn't a '9' directory, there are explicit instructions for adding a 'sources.list' file for Debian Stretch.

wget -O - https://download.gluster.org/pub/gluster/glusterfs/8/rsa.pub | apt-key add -
echo deb [arch=amd64] https://download.gluster.org/pub/gluster/glusterfs/8/LATEST/Debian/stretch/amd64/apt stretch main > /etc/apt/sources.list.d/gluster.list

Their download server gives this information about RHEL:

el6, el7, and el8 RPMs for RHEL, CentOS, and other RHEL Clones are available
from the CentOS Storage SIG.

Besides changing / updating the repository for packages, it looks like the current version of Gluster is "8" and so there may be changes to make to any systems using GlusterFS. (Note: Although I have GluserFS installed, this is a monolith installation and so I'm not using GlusterFS)

glusterfs --version

glusterfs 7.6
