Public bug reported:
The chromium.launcher process stays alive after the browser and its
processes terminated
This affects the following transitional package version (that points to
a snap):
$ apt-cache policy chromium-browser
chromium-browser:
Installed: 80.0.3987.163-0ubuntu1
Candidate: 80.0.3987.163-0ubuntu1
Version table:
*** 80.0.3987.163-0ubuntu1 500
500 http://de.archive.ubuntu.com/ubuntu focal/universe amd64 Packages
100 /var/lib/dpkg/status
$ lsb_release -rd
Description: Ubuntu 20.04 LTS
Release: 20.04
Steps to reproduce:
1.) Ensure chromium is not running:
$ ps aux | grep chromium | grep -v grep
$
2.) Start chromium browser using the launcher
3.) Verify running processes:
$ ps aux | grep chromium | grep -v grep | awk '{print $11,$12}'
/snap/chromium/1105/usr/lib/chromium-browser/chrome--no-default-browser-check
/bin/sh/snap/chromium/1105/bin/chromium.launcher
/snap/chromium/1105/usr/lib/chromium-browser/chrome --type=zygote
/snap/chromium/1105/usr/lib/chromium-browser/chrome --type=zygote
/snap/chromium/1105/usr/lib/chromium-browser/chrome --type=gpu-process
/snap/chromium/1105/usr/lib/chromium-browser/chrome --type=utility
/snap/chromium/1105/usr/lib/chromium-browser/chrome --type=renderer
/snap/chromium/1105/usr/lib/chromium-browser/chrome --type=renderer
/snap/chromium/1105/usr/lib/chromium-browser/chrome --type=renderer
4.) Close chromium
5.) Check for lingering processes:
$ ps aux | grep chromium | grep -v grep | awk '{print $11,$12}'
/bin/sh /snap/chromium/1105/bin/chromium.launcher
If you restart chromium multiple times, more launcher processes will linger
around in the system.
My expectation would be that the launcher process terminates after the
main chrome process is terminated.
