Error during upgrading: upgrade failed: another operation (install/upgrade/rollback) is in progress
While upgrading one of our clusters, we ran into this problem twice with metallb.
The HelmRelease would fail to upgrade, with status
upgrade failed: another operation (install/upgrade/rollback) is in progress
This seems to be an instance of this flux issue. We're not sure what in our setup triggers this.
We should document the solution in the troubleshooting guide, and point to it from the upgrade guide.
