Comment 13 for bug 1644643

Julian, I get something similar, but different.
"# apt
apt: relocation error: /usr/lib/x86_64-linux-gnu/libapt-private.so.0.0: symbol _ZN9pkgSystem9LockInnerEv, version APTPKG_5.0 not defined in file libapt-pkg.so.5.0 with link time reference"

apt-cache policy is the same, and so is apt libapt-pkg5.0.

What can I do to rectify this? I started asking on reddit, got redirected to askubuntu, and someone pointed me to this page, I was the one who confirmed it, as I experienced the same or similar issues.

I am contemplating reinstalling as using the same install media in a VM (mini.iso) resulted in a working state, and apt functions as expected, so I doubt the .deb files are the issue here, more likely the state of apt on my box.
