Having recently discovered Apache Guacamole, I thought it would be useful to have it hosted on my server to enable me to RDP and SSH via a web browser so installed it on a CentOS 7 VM.
I initially had trouble getting RDP to work but came across a post which said I needed to uninstall the version of FreeRDP, install an older version of FreeRDP, and then exclude FreeRDP from any updates by editing etc/yum.conf.
I've noticed that if I update and upgrade using yum and then restart the VM I am then unable to login to Guacamole afterwards. Here is what is available to update:
Looking at this list does anyone know what would stop me being able to login after installing these updates? Guacamole uses MariaDB and Tomcat if it helps.
If I check /var/log/messages I can see this:
Tomcat service is enabled and running if I run:
If I shut the VM down and restore a snapshot before these updates are installed I can login fine.

Is this ok [y/d/N]:
Looking at this list does anyone know what would stop me being able to login after installing these updates? Guacamole uses MariaDB and Tomcat if it helps.
If I check /var/log/messages I can see this:
WARN o.a.g.r.auth.AuthenticationService - Authentication attempt from <My Desktop IP> for user "david" failed.
Tomcat service is enabled and running if I run:
Code:
systemctl is-active tomcat
systemctl is-enabled tomcat
If I shut the VM down and restore a snapshot before these updates are installed I can login fine.
