^{ERROR imageService[<UUID>] [imageService 628] Failed to validate depot: ('zip:/storage/updatemgr/patch-store-temp/vum<FILENAME>.zip?index.xml', '', 'Could not download from depot at zip:/storage/updatemgr/patch-store-temp/vum<FILENAME>.zip?index.xml, skipping ((\'zip:/storage/updatemgr/patch-store-temp/vum<FILENAME>.zip?index.xml\', \'\', \'Error extracting index.xml from /storage/updatemgr/patch-store-temp/vum<FILENAME>.zip: "There is no item named \\\'index.xml\\\' in the archive"\'))')}

Cause

The offline depot file being used is either corrupt or not an offline bundle file which is indicated in the logs by the missing index.xml file which is expected in the offline.zip file. 

Resolution

Ensure the correct offline log bundle is being used and the provided checksum matches the downloaded file.
