[Intelmq-users] IntelMQ on CentOS7 - yum update failling with conflicting files

[Marco Paulo Machado Teixeira]

Hello Sebastian,
Thank you for you help.

Should have mentioned that already tried that, but dependencies ask to remove IntelMQ... Would you say it's safe to force removal of the package, ignoring dependencies, and just install the EPEL packet afterwards?

I haven't even updated the RPM repository yet with the 2.2.0 release.

and HOME:SEBIX:INTELMQ repo, with the following error (first line only, several more lines below I didn't copy). Already searched the web without luck. Also tried using REPO priorities but did not solve it.
Anyone has some advice on the best way to fix this without ruining the RPM database consistency? Or maybe some pointers where to look?

You can remove python3-dnspython. 

Short explanation: In the past I had to package dnspython myself (package python3-dnspython), as EPEL/CentOS did not have that package. 
With CentOS' Python 3.6 Upgrade, EPEL ships dnspython itself (as package python36-dns). 

There's no RPM database consistency, just two packages with conflicting files and RPM found and prevented the conflict, just as a good package manager should. 

best regards
Sebastian
