Looks to me like it's a problem with the init.d script. (See the attached "DpkgTerminalLog.txt" file:
start-stop-daemon: matching only on non-root pidfile /var/run/sendmail/mta/sendmail.pid is insecure Some other packages had similar problems (exim, amavis_d), but I'm not clear on how to correct this problem (despite having tried several ways). And I'm stuck. Cannot complete a reinstallation of sendmail, cannot remove or purge it either. I get the above message (matching...is insecure) every time. Does someone have a workaround? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1822866 Title: package sendmail-bin 8.15.2-12 failed to install/upgrade: installed sendmail-bin package post-installation script subprocess returned error exit status 2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sendmail/+bug/1822866/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
