Package: git-annex Version: 6.20161012-1 Severity: serious git-annex no longer build in sid because we have moved to ghc 8 and with it persistent 2.6.
The reason git-annex conflicts with newer persistent is because esqueleto's upstream is MIA. However, we have patched our version of esqueleto to work with persistent 2.6, so git-annex.cabal could have a Debian patch along the lines of - persistent (< 2.5), + persistent >= 2.5 && < 2.7, HTH
