netdata-nightly-downgrade.sh

#/bin/sh

#
# This explicitly installs Netdata Agent version 1.40.0-2-nightly on Debian based systems.

apt-cache depends --recurse --no-recommends --no-suggests --no-conflicts --no-breaks --no-replaces --no-enhances netdata=1.40.0-2-nightly 2>/dev/null | awk '/Depends: netdata/{print $2"=1.40.0-2-nightly"}' | sort | uniq | xargs apt-get -y --allow-downgrades install
chown -f -R netdata:netdata /var/{lib,cache,run,log}/netdata
systemctl restart netdata

Drive-by comment: I don't know if xargs is available by default. If not, we could save this to a variable with | tr '\n' ' ' and expand it in apt-get.

This work-around for the problematic 1.40.0-6-nightly:

• Installs or downgrades netdata version 1.40.0-2-nightly and its plugin dependencies
• Fixes the permissions for all directories the Agent should access
• Restarts the Agent through systemd.

suggested downgrade to 1.40.02 worked
thanks
Your incident -handling is great! 🖐️

People having quoting issues because of the awk command may try this as a replacement:

grep 'Depends: netdata' | cut -d' ' -f 4 | sed 's/$/=1.40.0-2-nightly/'

Notice that he "Depends: " part is language dependent: in my Ubuntu 22.04 configured in Spanish I had to replace it with "Depende: "
