sync2aptly: Dump all mismatches, not just the first one #32
Description
Sometimes, sync2aptly fails with an error like this:
Package already exists with different key 'Parm64 foobar 1.2-3b1 3c119dba3f289f32
Once this issue is resolved, it sometimes fails with another error about another package. These iterations take a lot of time, so it would be more useful if all mismatches were printed at once for the server operator to deal with.
