I am running on Ubuntu 18.04.1 release 4.15.0-38-generic.



I know this or a similar question was asked a few months ago and there seemed to be a fix or a workaround in progress.

iF man-db 2.8.3-2ubunt amd64 on-line manual pager


Every time I run Software Updater or try to install a new package it takes forever, and the reason seems to be lots of core dumps. Here is a small sample:

I believe AppArmor was identified as a possible culprit by someone at Astrill but I am not using any package called Astrill VPN. I have Expressvpn, the Ubuntu network managers, pptp-linux and openvpn.



I have tried reinstalling man-db and apparmor but nothing changes.

  • Do you get the same results just running zcat? I assume so, but we should be sure. Might simplify things if you can just see the single failure and reproduce with a single command. Example: echo "This is a test" | gzip | zcat

  • No. Why did you 'assume so'? The result just returned "This is a test", as expected.

  • Because the output you show specifically complains about zcat over and over. Given you report that various parts of man-db are not at fault, testing your assertions are just a good idea.
