Other users of Debian might want to take notice that the path to place the files under for that distribution is /lib/systemd/system-sleep/, i.e. without the initial /usr. Although this actually is properly documented with the correct path in the man page, it is a detail which is easy to miss.
So you should be using /lib/systemd/system-sleep/ as you are using Ubuntu, which is a Debian-based system. If you are not using Ubuntu, why are you posting to an Ubuntu sub forum?
Exactly what apmcd47 already said: /lib/systemd/system-sleep/On_Resume.sh is not the same as /usr/lib/systemd/system-sleep/On_Resume.sh and you are simply debugging the wrong script.
#!/bin/sh
set -e
if [ "$2" = "hibernate" ] || [ "$2" = "hybrid-sleep" ]; then
case "$1" in
pre)
/usr/share/unattended-upgrades/unattended-upgrade-shutdown --stop-only
;;
esac
fi
I am not sure what that means: in post #6 you said your script is named /usr/lib/systemd/system-sleep/On_Resume. You need to not only move it to another directory (which would make it /lib/systemd/system-sleep/On_Resume) but also name it differently: /lib/systemd/system-sleep/On_Resume.sh Have you done both? If yes, there should at least be some message in /tmp/systemd_suspend_test_err.txt now, otherwise your script has most probably NOT run.

It not only looks differently - it is! It does something completely different: first, this script expects TWO parameters, not just one. If the second is not "hibernate" or "hybrid-sleep", it does simply nothing at all. Second, this script is most probably run by a different shell: /bin/sh instead of bash. Depending on what /bin/sh links to (in Ubuntu perhaps dash) this will not be dash. Third, even if this script would do something (which is now, given the parameters with which you called the first script, unlikely) it would be something completely different from what the first script does.
I know script is running because it creates the text file in the tmp directory.
Code:
#!/bin/bash
#
# located in /lib/systemd/system-sleep/
# Created 4/2/19
exec 2> /tmp/systemd_suspend_test_err.txt
if [ "${1}" = "pre" ]; then
# Do the thing you want before suspend here
echo "we are suspending." > /tmp/systemd_suspend_test.txt
/usr/bin/gxmessage -fg red -font 'sans 30' -timeout 3 'Fixing to suspend computer.'
elif [ "${1}" = "post" ]; then
# Do the thing you want after resume here
sleep 5
echo "and we are back from being suspended" >> /tmp/systemd_suspend_test.txt
/usr/bin/gxmessage -fg red -font 'sans 30' -timeout 3 'Back from being suspended.'
fi
I'm not familiar with gxmessage, but from what we are seeing in the log, one might guess that some service it depends upon has already been shutdown before your script is called when the system is suspending and that the service hasn't been restarted yet before your script is called when the system is coming back up.
At least now we know what arguments are being supplied to your script when it is invoked.
Don't forget to remove your temp files after you have examined what happened after your script is invoked.

Hi,
I am trying to get squid up and running using a redirector process, and every time I try to load a web page, squid fails miserably.
Can some one with perl and squid knowledge take a look at these codes and tell if something is wrong here.

Hello,
is it possible to debug a script that is already running "on-demand"?
Somehow a command like "set -x" but once you've executed the script. And another one to disable debugging?
Thank you (0 Replies)
