[Bug 1990141] Re: Split-DNS not working in vpnc-scripts after renaming systemd-resolve to resolvectrl

[Heinrich Schuchardt]

Hello Michael,

thank you for reporting the issue. According to your description the
problem is with package vpnc-scripts and not ubiquity.

Could you, please, describe how to set up and test a split DNS scenario.

Best regards

Heinrich

Title:
  Split-DNS not working  in vpnc-scripts after renaming systemd-resolve
  to resolvectrl

Status in ubiquity package in Ubuntu:
  Incomplete

Bug description:
  Setting up a VPN with openconnect and split DNS is not working
  correctly after dist-upgrade from 21.10 to 22.04. The vpnc-script
  still refers to "systemd-resolve" to check for systemd-resolved and
  fails due to the name change to "resolvectl". Thus the DNS servers are
  written into the resolve.conf and thus breaks the split DNS
  functionality.

  As a quick workaround it was sufficient to create a symlink: 
    sudo ln /usr/bin/resolvectl /usr/bin/systemd-resolve

  As fix I would suggest to update the vpnc-script to use "resolvectl".

  Source: /usr/share/vpnc-scripts/vpnc-script line 143:

  grep '^hosts' /etc/nsswitch.conf 2>/dev/null|grep resolve >/dev/null 2>&1 && command systemd-resolve --status >/dev/null 2>&1
  if [ $? = 0 ];then
  	RESOLVEDENABLED=1
  else
  	RESOLVEDENABLED=0
  fi
