Accidently I corrupted my nsswithch.conf file and now my hosts are not working. How can I restore or recreate it?

  • `grep nsswitch.conf /var/lib/dpkg/info/*.postinst` leads to `/var/lib/dpkg/info/base-files.postinst` and `/var/lib/dpkg/info/libc-bin.postinst`, which lead to `/usr/share/libc-bin/nsswitch.conf` and `/usr/share/base-files/nsswitch.conf`. The `libc-bin` post-installation script is more specific, so I'd use that. – muru Mar 23 '17 at 05:52
  • @muru it may also be modified by the `libnss-mdns` postinst I think – steeldriver Mar 23 '17 at 10:40
  • This question is not a question of [that other question](https://askubuntu.com/questions/627017/how-do-i-recover-the-default-version-of-some-configuration-file), because the solutions listed there do not work for `/etc/nsswitch.conf`. Indeed, `dpkg -S /etc/nsswitch.conf` does not return any results (on Artful). – Bram Geron Nov 01 '17 at 16:34

This file is relatively generic, I would copy it from a working system of the same Ubuntu release

This should at least get you going - it's the default from xenial and should work regardless on pretty much any version.

# /etc/nsswitch.conf
#
# Example configuration of GNU Name Service Switch functionality.
# If you have the `glibc-doc-reference' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.
