This has just happened again. I was doing normal updates via GUI as requested by the operating system and it got stuck once again ath php7.0-xml configuration.
Found a process "php7.0-xml.postinst", killed it, update was able to continue.
Launched "apt upgrade" from command line and everything went fine (package configuration was done in seconds).
