------------------------------
I ran into the exact same problem during the upgrade from 4.1.0 to 4.3.1
release version output:
{code:java}
kafka-features.sh --bootstrap-controller $BOOTSTRAP_SERVER:$CONTROLLER_PORT
--command-config $COMMAND_CONFIG_PATH upgrade --release-version 4.3

all features since the following feature had an error: Invalid update version

[~rsommer] I didn't archive to read my snapshot to see if something looks odd
(like a stale registered controller) could you share your full command ?
if someone have any clue or hint it would be appreciated !

> Key: KAFKA-20295
> URL: https://issues.apache.org/jira/browse/KAFKA-20295
> Project: Kafka
> Issue Type: Bug
> Components: controller
> Environment: Kafka 4.2.0 (Scala 2.13) running on Debian Trixie 13.3
> Reporter: Roland Sommer
> Priority: Major
>
> While upgrading our kafka clusters to new operating systems I switched to
> dynamic voter configuration and removed controller instances with
> {{/opt/kafka/bin/kafka-metadata-quorum.sh}} and the {{remove-controller}}
> subcommand. Inspecting the cluster with {{describe}} only shows the actual
> running nodes.
> Now during the update to 4.2.0, the final metadata upgrade step complains
> about
> {code:java}
> Could not upgrade eligible.leader.replicas.version to 1. The update failed
> for all features since the following feature had an error: Invalid update
> version 29 for feature metadata.version. Controller 351 only supports
> versions 7-27{code}
> with 351 being an ID of an already removed controller. Inspecting a snapshot
> with {{/opt/kafka/bin/kafka-metadata-shell.sh}} indeed shows all controller
> ids of already removed controllers:
> {code:java}
> >> ls image/cluster/controllers/
> 158 206 351 584 611 686 {code}
> while other tools only show the expected nodes:
> {code:java}
> ~$ /opt/kafka/bin/kafka-metadata-quorum.sh --bootstrap-controller
> localhost:9093 describe --replication --human-readable
> NodeId DirectoryId LogEndOffset Lag LastFetchTimestamp LastCaughtUpTimestamp

> Is there any clear path for removing those stale nodes?
