Software center emails have stopped

NethServer Version: 7.7.1908
Module: software center

Since I’ve updated my system to 7.7.1908 the software center update notifications have stopped. This happened before i upgraded to Cockpit so i think the bug is somewhere in the 7.7.1908 update and not cockpit.

System > software center > config is configured to send admin emails
System > settings > Smarthost is configured
System > settings > email notifications is configured to send messages to me

I’ve tested email notifications using the old server manager, and messages get through. However the software center is not sending notifications.

Everything worked fine prior to upgrading to 7.7.1908


Seeing as you are now on the latest version, exactly what e-mails do you think you should be receiving. You should only get them if there are installed components that have a pending update.


I doubt it’s a bug, I’ve gotten emails from several upgraded machines over the last couple of days without any changes post upgrade.

That’s a good point!!!
Before I updated to 7.7.1908 I used to get email notifications if there were ANY updates available, I can’t remember the exact wording of the emails (I’m at work), but it was something like
Yum: Updates available

The notification emails were sent to root@nethbox and the root user was redirected to actualuser@nethbox, the messages would arrive in my inbox everyday if there were updates to install.

So far, 7.7.1908 has not sent any update emails, even though there are updates available (some for webtop and some for cockpit)

How are the update notifications supposed to behave with version 7.7.1908?

@fasttech my system is a standard nethserver install with subscription. I’m not sure what’s happened, but the behavior is different now the system has updated to 7.7.1908


This thread might help explain what you are seeing, due to your subscription.


Thank you for the thread reference, that doesn’t explain what’s happened.
I used to get software center update messages, now i don’t. The only difference is the update to 7.7.1908.
Here is an example of the emails i used to get:

Software center currently shows 21 updates are available, but i’ve not recieved any email. 4 updates are “nethserver” items, 17 updates are “base system” items.

AFAIK it’s down to 2 things, because you have a subscription.
Firstly, if you query the updates via the UI it will always show what’s available to update, regardless of when it was added to the repository.
The e-mail will only show what’s been available for a certain length of time (can’t remember the exact time) so that, as a subscriber, you only see them after they’ve been validated as not causing issues.

oh…that’s a surprise. The previous version never did that. I guess I’ll have to wait and see how long it takes to send me a notification.

I’ve been investigating this problem.
I’ve been following the guide here:

If I change the random_sleep time to 0 and run
yum-cron /etc/yum/yum-cron.conf
I get an email notification

This is the contents of /etc/cron.daily/0yum-cron on my system

# Only run if this flag is set. The flag is created by the yum-cron init
# script when the service is started -- this allows one to use chkconfig and
# the standard "service stop|start" commands to enable or disable yum-cron.
if [[ ! -f /var/lock/subsys/yum-cron ]]; then
  exit 0

# Action!
exec /usr/sbin/yum-cron

Should the last line be

exec /usr/sbin/yum-cron /etc/yum/yum-cron.conf

For reference, this is the contents of /etc/cron.hourly/0yum-hourly.cron

# Only run if this flag is set. The flag is created by the yum-cron init
# script when the service is started -- this allows one to use chkconfig and
# the standard "service stop|start" commands to enable or disable yum-cron.
if [[ ! -f /var/lock/subsys/yum-cron ]]; then
  exit 0

# Action!
exec /usr/sbin/yum-cron /etc/yum/yum-cron-hourly.conf

Please note the last line is different.

many thanks

/etc/yum/yum-cron.conf is the default value if no parameter is passed. From /usr/sbin/yum-cron:

default_config_file = '/etc/yum/yum-cron.conf'


OK, I see the default_config_file option in /usr/sbin/yum-cron

If I set




and then run yum-conf from the command line (whilst logged in as root), i get an email notification with a list of updates.

The run-parts(/etc/cron.daily) log shows that 0yum-daily.cron was started and stopped at about 3:30am, but i did not receive an email.

Something is not working properly since the update to 7.7.1908

If I manually start yum-cron, i get an update email. If the scheduled task 0yum-daily.cron is left to run, I don’t an email.
