For those who filed bugs I just duped here, there seems to be an underlying issue with update-manager invoking aptdaemon which in turn seems to think it needs to call a maintscript (although it doesn't necessarily) which then errors out.
Using cli tools instead, this does not occur. This is not specific to php7.0 at all, but is something seen across many packages always involving update-manager. I have seen at least a few historic bugs (supposedly fixed) and am still doing archaeology to see if something maybe was dropped: LP: #804250, LP: #779970, LP: #845367. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to debconf in Ubuntu. https://bugs.launchpad.net/bugs/1646739 Title: package php7.0-xml 7.0.13-0ubuntu0.16.04.1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 128 Status in debconf package in Ubuntu: Confirmed Status in php7.0 package in Ubuntu: Confirmed Status in update-manager package in Ubuntu: Confirmed Bug description: During a software upgrade, process was stuck on php7.0-xml configuration for 20 minutes, after that I killed the process.
