I'm marking this bug as Invalid for openssl due to the discussion above and the following line in DpkgTerminalLog.txt:
Unknown terminal: st-256color Debconf/whiptail failed and the issue seems to be in the machine configuration and/or whiptail/debconf rather than openssl. I'm not able to comment on the current status of these however. ** Changed in: openssl (Ubuntu) Status: Confirmed => Invalid -- 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/1703866 Title: package libssl1.0.0:amd64 1.0.2g-1ubuntu4.8 failed to install/upgrade: subprocess installed post-installation script returned error exit status 255 Status in debconf package in Ubuntu: Confirmed Status in openssl package in Ubuntu: Invalid Bug description: Was just trying to upgrade from 14.04 to 16.04 and the installer reported that issue and asked me to fill this...
