 Description   

Steps to reproduce:

NOTE: We are using zabbix 6.2.3 but I cannot select that version on the form.

 

We use a slightly customized dockerfile to pull the latest version of web image from dockerhub: zabbix/zabbix-web-apache-pgsql:ol-6.2.3, then we update it:

```

  1. install latest version of postgres13.X + update the image 
    USER root
RUN \
    cd /tmp/ && \
    curl https://download.postgresql.org/pub/repos/yum/reporpms/EL-7-x86_64/pgdg-redhat-repo-latest.noarch.rpm -o postgres.rpm && \
    rpm -i postgres.rpm && \
    microdnf remove postgresql && \
    microdnf module reset postgresql && \
    microdnf module enable postgresql:13 && \
    microdnf install postgresql && \
    microdnf update
USER zabbix

    ```

Result:
When launching the container, the following logs are produced, and the web container fails to load the UI:

```

```
Expected:
Zabbix web loads correctly. 

Note we have been patching containers for a while now, and this is the first time we ran into this issue.

What you do not like with currently installed PostgreSQL client?

Comment by Steve [ 2022 Dec 24 ]

The old client had some vulnerabilities, but they actually should be fixed now as per https://support.zabbix.com/browse/ZBX-21727 but I just never removed that step from my Dockerfile.

 

But it's not the postgres install part that is the issue here, it is doing the microdnf update, which is updating PHP and PHP FPM (I believe).

Also you are trying to install EL7 package on OL8
