Comment # 12 on bug 1221322 from Michael Andres

The broken virtiofsd package (#1220592) fails to install. CLASSIC_RPMTRANS
offers to abort/retry/ignore. Choosing ignore to see if at lest the remaining
packages can be installed is often a better choice. But the transaction was
aborted before zypper was updated as well.

To fix the system they may need to download and install these packages manually
(e.g. with curl and rpm):

  libprotobuf-lite25_2_0
  libsolv-tools
  libzypp
  zypper

Maybe missing additional dependencies as well.
