Looks like zesty switched to clang 4.0 today, which caused it.

[Daniel van Vugt (vanvugt)]

Looks like a disagreement between fixed capnproto code and clang 4.0. There's possibly nothing Mir can do to fix it.

Note capnp has been fixed upstream:

https://github.com/sandstorm-io/capnproto/commit/0f1fd1938b19dccdb5dbfe9cb5177c4342a2a5b5

[Launchpad Janitor (janitor)]

This bug was fixed in the package capnproto - 0.5.3-2ubuntu2

---------------
capnproto (0.5.3-2ubuntu2) zesty; urgency=medium
