18.04 to 20.04 Upgrade Notes

  • Upgrading might break your local resolver, DNSMasq. When you issue the command systemctl status dnsmasq, you might get an error that looks something like, dnsmasq: cannot access /etc/dnsmasq.d/lxd: No such file or directory. DNSMasq does not start because it cannot find this file. This file is simply a dangling symlink that needs to be removed, rm /etc/dnsmasq.d/lxd.
