A one more quick issue I came across at work during my SSIS deployment experience, is when I was trying to deploy my ISPAC (and similar error when I was trying to export the deployed package from SSISDB catalog), is the following error:
And the way around the above, was made possible was by the following set of statements, which re-setted the SSISDB catalog master password and was all green for my deployment there after…
USE [SSISDB] OPEN master Key decryption by password = 'Password' -- Password used when creating SSISDB ALTER Master Key ADD encryption by Service Master Key
Possible Reason for the above (a shot in the dark) could be, in the last week the servers were migrated.

To read more about the database Master Key please refer to the following MSDN Article
SQL Server and Database Encryption Keys (Database Engine)

Hope it helps !!!
