I do have this error today while building my container:
installing grafana-clock-panel @ 1.0.3
from: https://grafana.com/api/plugins/grafana-clock-panel/versions/1.0.3/download
into: /var/lib/grafana/plugins
Installed grafana-clock-panel successfully
Restart grafana after installing plugins .
installing briangann-gauge-panel @ 0.0.6
from: https://grafana.com/api/plugins/briangann-gauge-panel/versions/0.0.6/download
into: /var/lib/grafana/plugins
Error: ✗ failed to download plugin archive: Failed to send request: Api returned invalid status: 500 Internal Server Error
I didn’t have any issue yesterday, do you have some server issue on your end?
Thanks
Cyril
