Error: OPERATION instances must only be created through MAKE-OPERATION.
[condition type: FORMATTED-SYSTEM-DEFINITION-ERROR]
Is that an ASDF issue? Ceramic? ACL? cffi-grovel (the system being built when the error is thrown)?
You need a fresher version of cffi-grovel. Update your quicklisp and/or make sure you don't have an antique version of cffi in your local-projects and/or source-registry.
Does quicklisp use its own copy of ASDF for stability?
quicklisp provides an antique asdf 2.26 that is only loaded in even more antique implementations. All maintained implementations have been providing asdf 3.1 or later for over a year.
