Comment # 5 on bug 1035338 from Ignacio Taranto

This is the full message:
Problem: libstdc++6-devel-gcc6-6.2.1+r239768-5.5.2.x86_64 requires libstdc++6
>= 6.2.1+r239768-5.5.2, but this requirement cannot be provided
  uninstallable providers:
libstdc++6-6.2.1+r239768-5.5.2.x86_64[opensuse-update]
 Solution 1: deinstallation of libstdc++6-devel-gcc6-6.2.1+r239768-3.3.x86_64
 Solution 2: deinstallation of libstdc++6-gcc6-6.2.1+r239768-3.3.x86_64
 Solution 3: do not install patch:openSUSE-2017-404-1.noarch
 Solution 4: break libstdc++6-devel-gcc6-6.2.1+r239768-5.5.2.x86_64 by ignoring
some of its dependencies

I realized something, although the package libstdc++6-gcc6 does not have an
update for *5.2.2 version the package libstdc++6 does, but I don't have it
installed.

Both libstdc++6-gcc6 and libstdc++6 seems to be the exact same thing, could
this be a name collision?

I installed libstdc++6 which made me uninstall libstdc++6-gcc6  because they
were in conflict.

I installed also:
libasan3-6.2.1+r239768-5.5.2.x86_64 
libatomic1-6.2.1+r239768-5.5.2.x86_64
libcilkrts5-6.2.1+r239768-5.5.2.x86_64
libgcc_s1-6.2.1+r239768-5.5.2.x86_64
libgomp1-6.2.1+r239768-5.5.2.x86_64

libtsan0--6.2.1+r239768-5.5.2.x86_64
libubsan0-6.2.1+r239768-5.5.2.x86_64

which unintstalled:
libasan3-gcc6-6.2.1+r239768-3.3.x86_64 
libatomic1-gcc6-6.2.1+r239768-3.3.x86_64
libcilkrts5-gcc6-6.2.1+r239768-3.3.x86_64
libgcc_s1-gcc6-6.2.1+r239768-3.3.x86_64
libgomp1-gcc6-6.2.1+r239768-3.3.x86_64
libitm1-gcc6-6.2.1+r239768-3.3.x86_64
liblsan0-gcc6-6.2.1+r239768-3.3.x86_64
libmpx2-gcc6-6.2.1+r239768-3.3.x86_64
libmpxwrappers2-gcc6-6.2.1+r239768-3.3.x86_64
libtsan0-gcc6-6.2.1+r239768-3.3.x86_64
libubsan0-gcc6-6.2.1+r239768-3.3.x86_64

And that fixed the problem, I did zypper patch and the update went fine.
