Want to update APIC-EM version is 18.104.22.1689 to 22.214.171.1248 but after uploading it prints error "Release upgrade package file validation failed. File seems to be corrupted"
Tried to update to 126.96.36.1999 - same error.
md5 checksum - OK.
Check for the correct image for update you need to download the update package.
