Grafana has changed its signing key

Just a fri­end­ly tip:
If you are on Debian/Ubuntu and apt update complains:

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://packages.grafana.com/oss/deb stable InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 9E439B102CF3C0C6
W: Failed to fetch https://packages.grafana.com/oss/deb/dists/stable/InRelease The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 9E439B102CF3C0C6
W: Some index files failed to download. They have been ignored, or old ones used instead.

and assu­med your grafana.list looks simi­lar to mine:

deb [arch=amd64 signed-by=/usr/share/keyrings/grafana.gpg] https://packages.grafana.com/oss/deb stable main

then this will fix your problem:

wget -qO - https://apt.grafana.com/gpg.key | gpg --dearmor > /usr/share/keyrings/grafana.gpg

HTH and HAND

  1. Hal­lo Rainer,

    Graf­a­na beschreibt hier auch war­um. Bzw es gab einen Grund zum Prü­fen, kei­nen zum Wech­seln, aber sie haben es bei der Gele­gen­heit erledigt.

    1. Dan­ke, ich las von dem CI-Desas­ter, habe aber kei­ne Ver­bin­dung zu Graf­a­na gesehen.
