At least on buster/arm64 nothing depends on it. Was the package manually installed or does the description ring any bells?

Mine hangs because it's shutting down Firefox (Nightly from their website these days). Just as example, if I log out then log back in and run "ps aux|grep firefox" after logouts that take a long time, there will most likely be a long list of associated PIDs still in operation. If I try to launch Firefox at that moment, it will most likely fail with an advisement that a Firefox instance is already running. If I wait a few more seconds then try again, Firefox will FINALLY have shut down the rest of the way. It's been ages since I first realized that was occurring. It was an eye opener into that there's still a lot to learn about how operating systems and their packages work under the hood. :) Cindy :) -- Cindy-Sue Causey Talking Rock, Pickens County, Georgia, USA * runs with birdseed *

I've found that systemd takes down the network connections before it unmounts disks, so if I forget to unmount them before shutting down I get this delay. -- Tixy
Re: Stalled system shutdown
Just a question to help you start troubleshooting: Does the shutdown finish quickly/quicker if you first stop the ntopng systemd service manually before doing the full shutdown?

Stalled system shutdown
Hi, When shutting down, after upgrading to Debian 11, system shutdown hangs (freezes) for some time (about 1-2 minutes) anytime, making it bothersome to shut the system down. The freeze happens afther the "Stopped target remote filesystems" status line. After a while "A stop job is running for ntopng" is printed with an "in progress" status in red and a timeout of 1 minute 30 seconds, which is exhausted. So everyt time I shut down I get a 1 minute and 30 seconds delay. Anyone can help, please?
