The new

rdctl info

command in Rancher Desktop 1.21 is failing for users who have been upgrading Rancher Desktop from version 1.19.3 or earlier (or restored a snapshot that was based on an earlier installation). You can fix your setup by running:

console
rdctl shell sudo apk add iproute2

This fix will remain in place until you perform a factory reset, or restore from an older snapshot again.
