• The APS Catalog has been deprecated and removed from all Plesk Obsidian versions.
    Applications already installed from the APS Catalog will continue working. However, Plesk will no longer provide support for APS applications.
  • Please be aware: with the Plesk Obsidian 18.0.78 release, the support for the ngx_pagespeed.so module will be deprecated and removed from the sw-nginx package.

undefined symbol: apr_pool_pre_cleanup_register

Roy Boverhof

Basic Pleskian
As usual updating / upgrading Plesk failed:

[root@server tmp]# service httpd start
Starting httpd: /usr/sbin/httpd: symbol lookup error: /usr/sbin/httpd: undefined symbol: apr_pool_pre_cleanup_register
[FAILED]


For others that are struggling with this problem, the solution is quite simple:

[root@els011 tmp]# yum update apr

Oh... and upgrading from 10.2.0 to 10.3.0 will only work if 10.2.0 is fully updated. I wonder if any testing is done on these upgrades / updates at all... I actually can't recall any time when I simply updated the product and it worked without me having to apply database fixes, hack some config file or install missing packages!?

Anyway, I hope this helps someone.
