Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

In shell: $ uname -r 4.4.0-22-generic $ apt-get -s autoremove NOTE: This is only a simulation! apt-get needs root privileges for real execution.
