If your missing the retry button in SDDC manager lifecycle management, then on one of the bundles try this fix, I’d test it for the VxRail package however i’m assuming this will work for all packages that fail.
Run the “bundle_cleanup” utility on the SDDC Manager against the failed download:
/opt/vmware/vcf/lcm/lcm-app/bin/bundle_cleanup.py VXRAIL7-0-371-27538721DLD2323_VxRail-7-0-371-Composite-Upgrade-Slim-Package-for-7-0-x-zip

use the bundle ID:
