Before StackState version 1.14.2, some of the temporary files weren’t properly removed. This has been fixed in this release, but some older temporary files may still need to be cleaned up.
In order to remove them run:
rm -rfv /tmp/.sts
For upgrade instructions, refer to Upgrade StackState.
Important: If you plan to skip versions when you upgrade, ensure that you read the version-specific upgrade notes for each intermediate version. You may be required to perform manual actions as part of the upgrade.
