The system network services are not compatible with this version Ubuntu 14.04 problem to degradate libnl

by

After command: sudo dpkg -i lib*.deb

For files: 

libnl-route-3-200_3.2.21-1_amd64.deb
libnl-genl-3-200_3.2.21-1_amd64.deb
libnl-3-200-dbg_3.2.21-1_amd64.deb

I had a problem:

dpkg: error processing package libnl-3-200-dbg (--install):
 dependency problems - leaving unconfigured
dpkg: dependency problems prevent configuration of libnl-genl-3-200:amd64:
 libnl-genl-3-200:amd64 depends on libnl-3-200 (= 3.2.21-1); however:
  Version of libnl-3-200:amd64 on system is 3.2.21-1ubuntu1.

Even if I try to remove libnl before install:

$ sudo dpkg -r libnl-genl-3-200:amd64
dpkg: dependency problems prevent removal of libnl-genl-3-200:amd64:
 network-manager depends on libnl-genl-3-200 (>= 3.2.7).

dpkg: error processing package libnl-genl-3-200:amd64 (--remove):

Please help!

Solution from here – “The system network services are not compatible with this version” – ubuntu 14.04

Answer

I had this issue with a VMware guest. The root cause is that I had the trusty-proposed repository enabled. I personally won’t do that again. My resolution was to re-install. An option I took as it was a test virtual. As I understand it, a fix for a physical machine would be to sneakernet across the previous deb files to roll back the upgrade that broke your networking and sudo dpkg -i to install them.
