• 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.
  • Upgrading a VM might give you multipath errors in /var/log/syslog:

    VMWare does not pass information needed by udev. To fix this, go to your VM SettingsVM Options tab → AdvancedEDIT CONFIGURATION.

    Add the parameter, disk.EnableUUID and set the value to TRUE. The VM must be powered off to add a new parameter. Reboot your system again and you should no longer receive these errors.
