[Bug 1871615] Re: package apparmor 2.13.3-7ubuntu4 failed to install/upgrade: end of file on stdin at conffile prompt

[Launchpad Bug Tracker]

This bug was fixed in the package unattended-upgrades - 2.3

---------------
unattended-upgrades (2.3) unstable; urgency=medium

  * Fix checking if Python regexp is also a POSIX regexp
  * Prepend implied '^' when converting Python regex to a POSIX one
  * Blacklist not trusted packages and ones with conffile prompts
    instead of just pinning them once with NEVER_PIN which is can be cleared
    later. (LP: #1871615) (Closes: #956339)
