error processing latest versions in %q: %v

Error message

error processing latest versions in %q: %v

What it means

Returned by buildMenu while iterating a channel's version entries to build the upgrade menu: one of the versions in the named channel could not be parsed or resolved (malformed semver, missing key/version digits, or an unreadable version resource). %q is the channel location; %v is the underlying parse or I/O failure.

Solutions

1. Inspect the channel YAML at the quoted location and fix or remove the broken entry in its versions list
2. Verify the channel URL is reachable and serves valid YAML (fetch it and run it through a YAML/semver validator)
3. Pin to a known-good upstream channel while the custom channel is repaired
