Helm upgrade failed another operation is in progress

1

Some time ago I did an upgrade to rancher v.2.8.2 which at first sight happened successfully.
But now that I want to do an upgrade to v2.8.3 helm gives the following error.

rancher Error: UPGRADE FAILED: another operation (install/upgrade/rollback) is in progress

I did some digging around and came with the following information.

helm history -n cattle-system rancher
REVISION UPDATED STATUS CHART APP VERSION DESCRIPTION
1 Mon Nov 27 13:25:44 2023 deployed rancher-2.7.9 v2.7.9 Install complete
2 Thu Mar 14 13:30:54 2024 pending-upgrade rancher-2.8.2 v2.8.2 Preparing upgrade

helm ls -a -n cattle-system

NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION
rancher cattle-system 2 2024-03-14 13:30:54.905346542 +0100 CET pending-upgrade rancher-2.8.2 v2.8.2
rancher-webhook cattle-system 2 2024-03-14 12:34:35.935552673 +0000 UTC deployed rancher-webhook-103.0.1+up0.4.2 0.4.2

As you can see the current version i’m using for some time now v2.8.2 is still in “pending upgrade”

kubectl get secret -n cattle-system -l status=pending-upgrade
NAME TYPE DATA AGE
sh.helm.release.v1.rancher.v2 helm.sh/release.v1 1 46d

Any idea how to solve this? I also rather not do a rollback if possible since v2.8.2 is working fine for the rest.

I deleted the secret wich also means helm has no idea about revision 2 anymore but this way I was able to upgrade my cluster. Not sure if this was the right way to do it but because these issues aren’t really documented anywhere I gave it a shot and so far it works.
