CentOS update breaks Nextcloud authentication


CentOS 7.6.1810
PostgreSQL 11.2
PHP 7.3.4
Nextcloud 16.0.4

After performing CentOS update using “yum update -y” Nextcloud user logins stop working through the web interface and password reset cannot be completed as Nextcloud reports that it cannot send emails. Password reset worked fine prior the update.

I easily go back to working state using VM snapshot but don’t want to leave the OS unpatched.

Can you point me in the right direction to troubleshoot this issue?



(it’s only my first though because i’m just trying got this right in my playbboks…)

Thanks for the tip but selinux is disabled on this machine.

anything in the logs? (nextcloud.log, nginx, php-fpm, …)

Please could you also have a look into your /var/log/yum.log to see what has been updated? Maybe that gives a hint as well what is causing your issue.

Apart from that I agree with @Reiner_Nippes - It’s always practical to look into the log files of each piece of software you are using, as these might give you error messages, which in return could point you to the solution of the problem.

Unfortunately there are no error messages or entries in nextcloud, nginx and php-fpm log files that point to the cause of the issue. I wonder if it has to do with postgresql update.

Below is the list of packages that get installed as part of yum update. This is text copy from SSH session after “yum update” is issued but before confirmation with “y” (not from yum.log).

I came to realization that php updates are causing the issue. List of packages below. Also to mention that Opcache and Redis are used as part of server optimization. I wonder if anyone has any ideas on what the solution might be now that I narrowed the issue down?

yum install php-cli php-common php-devel php-fpm php-gd php-intl php-json php-mbstring php-mysqlnd php-opcache php-pdo php-pear php-pecl-apcu php-pecl-apcu-devel php-pecl-igbinary php-pecl-imagick php-pecl-redis4 php-pgsql php-process php-xml

php update changed ownership of /var/lib/php/session directory

chown -R nginx:nginx /var/lib/php/session
