It still doesn't work in ubuntu 16.04 server.

It seems that the ovs (both branch-2.5 and master) cannot be compiled and packaged in deb.

[Li Ma (nick-ma-z)]

The temporary work-around:

The ovs compilation requires automake package version 1.14. But with a recent update of ubuntu repo, the automake package is updated to 1.15 which is incompatible with ovs. As a result, the compilation is failed.

I hacked the ubuntu to fix the problem:

cd /usr/lib
ln -s aclocal-1.15 aclocal-1.14
ln -s automake-1.15 automake-1.14

I will provide a patch to guarantee the automake version is 1.14 in the ubuntu system.

[Li Ma (nick-ma-z)]

After fixing the automake version problem, the compilation still failed in auto test.

debian/rules:37: recipe for target 'override_dh_auto_test' failed
make[1]: *** [override_dh_auto_test] Error 1
make[1]: Leaving directory '/opt/stack/ovs'
debian/rules:25: recipe for target 'build' failed
make: *** [build] Error 2

My environment is Ubuntu 16.04 server. Actually, Ubuntu 16.04 supports OVS 2.5 already. So, it doesn't need to compile ovs from soruce in devstack. We can directly install packages from Ubuntu repo.
