This job ran while we were trying to transition to mariadb 10.1.30 in RDO [1]

We found out that this specific package has an issue which caused net-snmp to fail to install.

Haikel built a new version of the package mariadb-libs-10.3.10-1.el7.0.0.rdo2.x86_64 and I can now install both mariadb and net-snmp on the same standalone centos environment [2], whereas I couldn't do it with the former rpm.

So I think this was a transient error and it should fixed now

@Damien: I am glad it was already fixed. Now my question is if rdo package building has a CI job that tests for this kind of conflict?

This is quite important in order to avoid similar issues in the future, especially as I seen an almost identical issue from 2016. If conflicts are detected before a new version is releases, we can avoid breaking consumers of rdo repos.

net-snmp is not really an esoteric library which nobody would expect to be installed.
