Update Grafana and Influx

[s4en]

I always update the containers with the command apt update && apt upgrade -y.
But now I get the following error message with Grafana and Influx:

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://repos.influxdata.com/debian bullseye InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY XXXXXXXXXXXXXXXXX
W: Failed to fetch https://repos.influxdata.com/debian/dists/bullseye/InRelease The following signatures couldn't be verified because the public key is not available: NO_PUBKEY XXXXXXXXXXXXXXXXXXXXX
W: Some index files failed to download. They have been ignored, or old ones used instead.

To correct the issue, you can execute the install command within the LXC console (needed only once).

Thanks for the answer but i running in problems:
Grafana works but in Influx i got this:

✗ No InfluxDB Installation Found!

But i can start influx and it works

Run the following commands in the InfluxDB LXC console

wget -q https://repos.influxdata.com/influxdata-archive_compat.key
cat influxdata-archive_compat.key | gpg --dearmor | tee /etc/apt/trusted.gpg.d/influxdata-archive_compat.gpg > /dev/null
echo 'deb [signed-by=/etc/apt/trusted.gpg.d/influxdata-archive_compat.gpg] https://repos.influxdata.com/debian stable main' | tee /etc/apt/sources.list.d/influxdata.list
rm -f /etc/apt/trusted.gpg.d/influxdb.gpg
apt-get update
apt-get -y upgrade
