Hello to all,
since Feb 2021 we have updated NS to 7.9.2009 & we had a subscription (Crostino). But from then I don’t get any mails from Software center, if there are updates available…
The checkbox in Software center configuration “Mail to System Admin” is checked. Other Mails to root/ admin are working, so I think the mail system is ready and works… We have also about 50 mail users. All mails from/ to users are working too - no errors.
What can I do? Can anyone give me some suggestions/ hints?
Thanks in advance
Hmm, there are 2 options at “Software center configuration”: 1) Download 2) Download and install.
My selection ist 1) (only download). I have had bad experiences with full automatic updates…
I can understand, it happened with me also. But don’t forget that you’re paying for delayed updates, after the community also used it and reported eventual issues.
Some additional information:
Last mail from NS regarding updates I’ve received on 09. Feb 21 from user ‘root’ with subject line “Yum: Updates Available on mail@xxx.de”. After that day we buyed & installed a subscritption und made update to NS 7.9.
Is there a way to reactivate this behaviour? Possibly configuration via the console (not from the cockpit menu)? Are cron or yum involved here?
The subscription doesn’t suppress any mail and yes, it’s something with yum-cron.
When yum-cron cron generates some output, cron will send the mail: I have plenty of them on my inbox from machines with subscriptions.
Take a look at yum-cron config, what’s the output of grep email /etc/yum/yum-cron.conf?
# How to send messages. Valid options are stdio and email. If
# to have cron send the messages. If emit_via includes email, this
# program will send email itself according to the configured options.
emit_via = email
[email]
# The address to send email messages from.
email_from = root@xxx-yyy.de
email_to = root@xxx-yyy.de m.matyssek@xxx-yyy.de
# Name of the host to connect to to send email messages.
email_host = localhost
Inside the folder /etc/yum/ I see two config files, yum-cron.conf and yum-cron-hourly.conf.
I have edited the file yum-cron-hourly.conf to to this:
Good morning to all!
New results from me: I did not receive mail from new updates, which are available on my NS.
I wonder if the cron job for yum updates is active… I should check this.
My log files are quite large, what should i look for to find failures in cron or yum regarding not sending mails if updates available?
Assuming updates are involved daily I’ve looked into folder /etc/cron.daily. There exists the file 0yum-daily.cron. Inside this file exec /usr/sbin/yum-cron is called. So far so good, but which config file is used for this call? In the web I have seen something like this:
First I have edited the file /etc/yum/yum-cron.conf to change parameter "random_sleep = 360" into "random_sleep = 0" (for test purposes only!).
After that I called yum-cron manually in a console with result:
Failed to send an email to localhost: {‘root@xxx-yyy.de’: (504, ‘5.5.2 : Sender address rejected: need fully-qualified address’)}
So the fact is yum-cron needs a fully-qualified address with myhost.mydomain.TLD!
