Try

# guix gc --verify

If that doesn't work, then

$ cp /var/guix/db/db.sqlite /tmp/
$ sqlite3 /tmp/db.sqlite
sqlite> .tables
sqlite> .schema Refs

Do you see a foreign key here with "on delete restrict", Refs.reference ?

sqlite> .schema DerivationOutputs

No "on delete restrict" here?

sqlite> .schema FailedPaths

No "on delete restrict" here?

sqlite> .schema ValidPaths

No "on delete restrict" here?

Also, is there a hash value somewhere in the error messages?
