package mythtv-common 2:30.0+fixes.20190817.5cde0578d8-0ubuntu3 failed to install/upgrade: installed mythtv-common package post-installation script subprocess returned error exit status 2

Permissions problem creating file in /tmp. I worked around it by temporarily removing the sticky bit on /tmp; this enabled the package to install, but is obviously unacceptable in a release package.

This occurred on upgrading a MythTV frontend box from Eoan to Focal development.
