Upgrade from 2.2.0 to 2.2.1 is broken

[brewsteropsdev]

Running a helm upgrade from 2.2.0 to 2.2.1 results in the following error:

Error: UPGRADE FAILED: cannot patch "nextcloud-dev" with kind Deployment: Deployment.apps "nextcloud-dev" is invalid: spec.selector: Invalid value: v1.LabelSelector{MatchLabels:map[string]string{"app.kubernetes.io/component":"app", "app.kubernetes.io/instance":"nextcloud-dev", "app.kubernetes.io/name":"nextcloud"}, MatchExpressions:[]v1.LabelSelectorRequirement(nil)}: field is immutable

Hi there! You will need to delete the existing nextcloud-dev deployment before running helm upgrade.
Something like kubectl delete deployment nextcloud-dev.
The changes in 2.2.1 do not require modifying your values.yaml or changing how you install the chart, which is why the major/minor versions were not bumped.
This is just an unfortunate restriction around modifying existing deployments in kubernetes.

If this is still an issue, perhaps it should go into the documentation? I am currently rounding up issues related to upgrades to better review and help with creating an upgrade section of our documentation. Anything I find, I put an upgrades label on, so that we can easily find them all.

I'm going to close this as stale since it's been a few years without a reply from the original poster and it concerns a chart version that is several major versions behind. If you're still having trouble with an upgrade from a more recent version to latest, we'd love to help you further.
