A known bug, (fixed in later OS versions), may cause the compatibility verification to fail with an "SRG file not present" error. The workaround is simple: run the upgrade command again . The failure is typically transient, and the second attempt usually completes successfully.
For those with eval licenses, Cisco sometimes hosts limited images on devnet.cisco.com, but production use requires a contract.
