Assuming what I found to be true ... this is not a bug with yum or
protectbase ... or even I problem with the repos individually ... but a
problem if dag and kbs are used together.
That being the case, neither repo taking action IS acceptable (as each
repo is OK individually, and this is a cross repo problem).
Therefore to fix this issue (if the repo maintainers have not / do not
update the repos ... or until they do) is to do this:
------------------------------------
If you want to use Dags repo for clamav:
in the kbs-CentOS-Extras repo add this line:
exclude=clamav*
-----------------------------------
If you want to use kbs repo for clamav:
in the dag repo add this:
exclude=clamd clamav*
-----------------------------------
As a side note, this kind of problem happens quite frequently when more
than one repo is used.
Thanks,
