I took our on-premises OVA to 3.0.0r26 just fine. I then tried to apply the package update of 3.0.3r17 and it fails with:
2021-07-19 22:22:34,929 - 772 - cns.hotfix - ERROR - CODE-1000: OVA version mismatched!, Current version: 3.0.0-r26. Supported versions - [‘3.0.0-r19’] !
Nothing I’ve tried has been successful. Current package version is 3.0.0r26 and nothing newer than that will install.
