Package: ntopng Version: 2.0+dfsg1-1 Severity: normal When upgrading from version 1.2.1+dfsg1-2 to 2.0+dfsg1-1, the postinst script hung. Note that this machine is still using sysvinit, not systemd. The relevant pstree output:
root@basil:~# pstree -ap 7441 aptitude,7441 -u ├─dpkg,19994 --status-fd 107 --configure libndpi2:amd64 libjs-bootstrap:all ntopng-data:all ntopng:amd64... │ └─frontend,20002 -w /usr/share/debconf/frontend /var/lib/dpkg/info/ntopng.postinst configure 1.2.1+dfsg1-2 │ └─(ntopng.postinst,20008) └─{aptitude},12945 Sorry, I did not notice if ntopng was running at this point or not, but I believe it was for two reasons. The output from aptitude at this point was Setting up ntopng-data (2.0+dfsg1-1) ... Setting up ntopng (2.0+dfsg1-1) ... [ ok ] Starting network top daemon: ntopng. At which point I killed frontend (20002) and aptitude continued with dpkg: error processing package ntopng (--configure): subprocess installed post-installation script was killed by signal (Terminated) and then later: Errors were encountered while processing: ntopng E: Sub-process /usr/bin/dpkg returned an error code (1) W: Operation was interrupted before it could finish Failed to perform requested operation on package. Trying to recover: Setting up ntopng (2.0+dfsg1-1) ... [ ok ] Starting network top daemon: ntopng already running.
