This is related to my recent question regarding how to upgrade php to 7.4, which is now locked:
https://support.nagios.com/forum/viewto ... 16&t=62768

After successfully upgrading to php 7.4, I attempted my first upgrade today. It failed due to what looks like problems with dependencies related to either the repos and/or the php version. Here is the log:

So, I was able to upgrade to 5.8.4, using the following commands, but this bypasses the need for php-imap, and I don't know how important that package is...

dnf config-manager --disable nagiosxi-deps
vi /tmp/nagiosxi/upgrade, and change the following line:
#yum install `yum list installed php*common* | grep php | awk -F "-" {'print $1'} | tail -1`-imap -y
yum install `yum list installed php*common* | grep php | awk -F "-" {'print $1'}` -y
dnf config-manager --enable nagiosxi-deps
...then restarting xi daemons

Since I'm working off a snap-shotted VM, I decided to chuck the RHEL repo supplied php, and switch over to the remi-7.4 stream, and this resolved my problems with ( php-imap , php-pecl-ssh2 ). I will be asking our RedHat Administrator permission to go this route, but I'm not sure what he'll say. He specifically told me a couple of weeks ago to NOT DO THIS.

The old PHP 7.2 packages must've still been installed if yum was failing on it. Or if the weren't maybe the cache was messed up for dnf/yum. You can try doing this before:
I'm going to try to replicate this.

This seems to be because the php-imap package isn't available in the standard repos and the only version that nagiosxi-deps has is php 7.2 so that won't work. That's likely why remi works as they have a replacement package for it.

You may need to reach out to RHEL on this to see if they can provide an official php-imap 7.4 package and a compatible version of php-pecl-ssh2 so your security team will approve it. I'm only able to get it to work with remi being used.

Thank you for the feedback!

I came to the same conclusion, that since Remi builds those missing 7.4 packages (php-imap, php-pecl-ssh2 (requires libssh2-1.9 from epel), and php-pdo-dblib) why fight with RHEL. I convinced our RedHat SA to let me switch to the remi repo, so all is well.

Lock it!
