Unexpected (auto-)update to 7.6.1810


(Davide Principi) #1
[root@vm5 ~]# rpm -q centos-release
centos-release-7-6.1810.2.el7.centos.x86_64

Looks like the “release lock” was enabled after the automated update… Really strange!


Samba asks for a password after update
NethServer Imap problem
New Centos 7.6 update
How to stick with the 7.5 version?

I did some tests because I thought there were problems with the updates, but after the problem

The changes at 4:06 were done automatically, the changes after 07:45 were done by me.

Please mark Oliver’s answer as topic solution!

Let’s see if the previous log files matche too…

 grep NsReleaseLock /var/log/messages-*

And also

 grep nethserver-check-nsreleaselock /var/log/cron*

This action was expected to switch the policy to “locked” automatically tonight :frowning:

https://github.com/NethServer/nethserver-base/blob/3.5.2/root/etc/cron.daily/nethserver-check-nsreleaselock

I’d say we’ve a #bug here: it runs after 0yum-cron! See ls -l /etc/cron.daily/.

Hi there,
We had the some prolem on 3 mail servers today. As temporary solution we disabled the dovecot antispam plugin. On

/etc/dovecot/dovecot.conf

we commented the lines about spam training. In this way we disabled the antispam plugin.

Afther that we restarted the dovecot services with

systemctl restart dovecot

(or via web interface) and with

systectl status dovecot

we verified that the error was gone away. In about 20 seconds the mail clients started to download the mails

I have no further occurrences of NsReleaseLock in older log files.

Yes, that seems to be the problem.


(Davide Principi) #7

This confirm my theory: the check action runs after yum updates!

I guess those who have yum-cron automated updates enabled are affected by this bug today…

I’m moving some posts under the #bug category


(Davide Principi) #8

(Marc) #9

Confirmed. I’d enabled automatic updates to be downloaded (not installed) and received two notification emails:

  • (Tue, 04 Dec 2018 04:14:17) yum update
  • (Tue, 04 Dec 2018 04:14:26) anacron /etc/cron.daily/nethserver-check-nsreleaselock

(Davide Principi) #10

I guess it’s too late to fix it :cold_sweat:


(Zimny) #11

I have got exactly the same problems on my servers :frowning:
and this is imap log about it

Error: Couldn’t load required plugin /usr/lib64/dovecot/lib90_antispam_plugin.so: Module is for different ABI version 2.2.ABIv10(2.2.10) (we have 2.2.ABIv36(2.2.36))


(Davide Principi) #12

This is a possible workaround


(Zimny) #13

Thank you for this workaround. It’s helped back email servers (dovecot exactly because postfix is not affected by this bug).


(Lorenzo) #14

We have just checked the configuration of one of servers which experienced this problem today. In the web interface it was configured to download the updates but not to installs them; but there was a crontab configuration which seemed to overrided the configuration in web interface: al 2 am of every day it was configured a cronjob which download and install the update
We perform a change in to

/etc/crontab

with

crontab -e

it do not show us the content of crontab so we used

vi /etc/crontab

that’s strange but so it is… For security we rebooted the server in order to understand if automatically our change to the crontab was overwritten by something but it was not.


(Davide Principi) #15

I’m pretty sure none of NethServer packages changes that file!

Please check /var/log/cron contents to understand what happened


(Lorenzo) #16

Well, i found out that it was a legacy of the old version of netheserver, when there were no automatic update via web interface. A coworker of mine setted up the cronjob so it now override the web interface config. We deleted the cronjob


(Davide Principi) #17

(Davide Principi) #18

The bug is tracked here:

If it is fixed, we’ll avoid update issues when CentOS 7.7 is out.


(Gabriel GHEORGHIU) #19

No issues (on NethServer release 7.5.1804 (final) ) with this configuration!


(Davide Principi) #20

Yes, only “Install updates automatically” enabled causes the problem…
